Adding Additional Devices

Mylio is designed to keep all of your photos with you on all of your devices all of the time. This means that getting Mylio installed on all of your devices is an integral part of the Mylio experience.

Mylio can be installed on Android, iOS, Mac, and Windows devices that meet Mylio’s system requirements. Each device can be used to store all original files, called a Vault, or sync with auto-optimized versions of your files to save space.

To better protect your photos you can add additional Vaults that have the necessary storage to want Original images. Alternatively, you can add a device to sync in auto-optimized quality so that you can show off your pictures wherever you are. To add a new device:

  1. Open the Dashboard.
  2. Select the Add button in the top right of the Devices section of the Dashboard.
  3. Mylio will offer recommendations for protecting your photos. These may include:
    1. Add Computer
    2. Add External Drive
    3. Add NAS
    4. Add Amazon Drive, Google Drive, or Microsoft OneDrive

Once selected, Mylio will guide you through getting started on these devices.


Mylio Sync Settings

Accessing Sync Settings from Mylio’s Settings
Mylio’s Sync settings menu allows you to view and manage all of your current Sync settings for your device. Sync settings can be accessed from two locations:

  1. Select the View menu (three vertical dots in the top-right).
  2. Select Settings
  3. Select Sync

Available Options:

  • Sync – Sync allows you to synchronize your photos across your Mylio devices.
  • Sync on Demand  – Sync Previews of files to devices that want Thumbnails (Auto-Optimized devices too) if a device that has Previews is online.
  • Sync with Cloud Services – Allow syncing to all cloud services on the account like Google and Amazon.
  • Device Sync Policy Settings – opens options to set a Custom Sync Policy for your device.
  • Hotspot– Create a network to sync devices when no internet is available.

Understanding Syncing with Mylio

Keeping all of your memories on all of your devices is easy with Mylio. Syncing allows each of your devices, whether it be computers, phones, tablets or external hard drives to always have the same information. Syncing also ensures that new photos added to one device are available on other devices and that edits, metadata, and organization changes made on one device are available on all of your devices.

How Syncing Works

Mylio syncs over a peer-to-peer connection to ensure that photos and videos are shared between your devices quickly and safely. Peer-to-peer means that your devices do not utilize the internet or the cloud to transfer photos. Instead, Mylio uses a direct wireless connection between your devices to sync information. Mylio gains this direct connection by looking at your devices on a network. This network can be a home wireless network, a wired/wireless hybrid network, or even an open Wi-Fi network (restrictions apply). Even though Mylio utilizes a network, it does not require the internet – simply that your devices be connected to the same network.

Mylio must meet three criteria in order to sync your devices:

  1. All devices must be logged into the same Mylio account.
  2. All devices must be connected to the same network.
  3. All devices must be running Mylio (Mylio must be in the foreground on mobile devices).

When these three criteria are met Mylio will transfer your photos, videos, edits, metadata, and organization between all of your devices quickly and safely.

Photo Quality Basics

In its default state, Mylio is designed for you to only need to answer one question:

Do I want to store all of my original photos on this device, or do I want Mylio to automatically optimize my images for me to save space?

If you choose to store all of your Original images as well as the Thumbnails and Previews on a device, you are creating a Mylio Vault. Vaults are designed to keep your information safe by keeping a copy of all of your files. And the more Vaults you have, the safer your photos are. Vaults can be any device that has enough storage to hold your entire photo library, but popular Vaults are cloud storage providers, external hard drives, NAS devices, and desktop computers.

Mylio has three different photo quality sizes that can be stored on your devices:

  • Thumbnails – A small version of your photos (20kb to 30kb) that is great for referencing your full library. Ideal for mobile devices. Does not allow editing.
  • Previews – Medium quality (approximately 1mb) that gives an accurate representation of your photos at a fraction of the space. Perfect for laptops. Fully editable.
  • Originals – Your full quality file (original file size). RAW compatible. Fully editable.

If you have told Mylio to automatically optimize the storage of your device, we’ll choose what photo quality we think you’ll want to see based off of specific criteria.

You can change a device between a Vault and Auto-Optimized quality by:

  1. Open Mylio and select the Dashboard in the top right corner.
  2. Select the device that you wish to change between a Vault and Auto-Optimized quality to open the Device Settings.
  3. Select Device Sync Policy Settings
  4. When viewing just the default Simple Device Settings, you can toggle between Vault and Auto Optimized as your desired quality. You can also create a Custom Device Sync Policy by toggling on Advanced Settings. 

Advanced Quality Settings

If you’re looking for a bit more control over how your images sync, then Mylio’s Advanced syncing options are for you.

When toggling on Advanced syncing options, Mylio allows you to change your device’s Sync Policy on a more granular level. Your device’s Sync Policy is what quality of photo your device will sync images in. Any new photo added to Mylio on another device will sync to this device in this quality.

To turn on Mylio’s Advanced sync options, simply:

  1. Open Mylio and select the Dashboard in the top right corner of Mylio.
  2. Select the device that you wish to change the Sync Policy of.
  3. In the Device Settings, toggle on the Advanced option under Device Quality to show Mylio’s advanced Sync Policies.

Mylio has three different Sync Policies:

  • Thumbnails – A small version of your photos (20kb to 30kb) that is great for referencing your full library. Ideal for mobile devices. Does not allow editing.
  • Auto-Optimized – Mylio will manage your library based on the available storage on your device.
  • Vault – All three file types are stored. Great for desktops.


To learn more about setting Custom Sync Policies, please see this article. Any Custom Sync Polices to the device or folders will override the sync policy set at the top of this window. You can reset any folders or cutom polices overriding the Device Sync Policy by selecting the “Reset Device Quality” button at the bottom.

Troubleshooting: Fixing Unprotected Images

In some circumstances, Mylio may display images as unprotected in the Dashboard or the Sync panel. This means that your photos are not on all devices that have a sync policy to “want” them. If some images are listed as unprotected, the steps below will help you identify images and get them protected across multiple devices.

  Note:   the steps below assume that you have at least a device set as a Vault. If no device is set as a vault then all images are marked as unprotected.

Identifying Which Photos Are Not Protected

  1. Open Mylio and select the Dashboard icon at the top corner.
  2. Select the “X Unprotected Images” text at the top of the Devices list.
  3. Mylio will display the images that are not protected across all devices.
  4. Select 1 of the images (or all of them)
  5. Open the Sync panel by selecting the two arrows in the top right of the Details panel.
      Note:  if you do not see the Sync Panel you can turn the feature in the Advanced section of the Device Settings.
  6. Using the Sync panel, locate the device that has a solid green line (or green squiggly line) under the Originals column. This is the device that has the Originals. If you do not see a device with green under Originals please see the next section of this article.
  7. While in the Sync panel, locate the device that has orange under Originals. This is the device that wants Originals.
  8. Bring both the device that has Originals and the device that wants Originals online by opening Mylio on both devices while they are on the same wi-fi network. If the device that wants Originals is an external drive, plug that drive into a computer and run Mylio on that device.
  9. Mylio will automatically protect the unprotected images.


Working with Photos That Do Not Have Originals On Any Device

If, when looking at the Sync panel, you cannot identify a device that has Originals (green line under Original) this means that the Original file is not available to Mylio and the file is not able to be protected. This can happen for multiple reasons:

  1. The file is missing and needs to be relinked. In this case, the folder that the file resides in should say Missing on it in red text. You can relink the folder to fix this.
  2. The Original file has been deleted from the initial device creating a Lost Original. This can happen most commonly on mobile devices if a photo has been deleted directly from the Camera Roll before Mylio has been given time to sync the original to another device.
  3. The library has been restored from a Time Machine or other backup, causing Mylio to know that is has images but doesn’t know where those images are.


Sync On Demand

Sync on Demand allows devices storing low-quality images (Thumbnails) to temporarily be shown a higher resolution version of the photo (Preview)without permanently taking up storage on their device.  Mylio will seamlessly sync a higher resolution version of a photo from a connected device when the file is viewed, and then cache the image for deletion when it is not being viewed.

For instance, if you are browsing photos on an iPad with low-quality images, while a computer with higher-quality images is connected, the higher-quality will automatically be sent to the iPad for viewing, and then removed from the iPad (cached) when navigated away from.

Turning on Sync on Demand

  • Navigate to Mylio’s Settings by selecting Settings from the View menu.
  • Select Sync.
  • Toggle on Sync on Demand.


Troubleshooting: Corrupt or Unsupported Files

In some cases, Mylio may report that images being imported or corrupt or unsupported. While this may happen for a variety of reasons, it is important to understand if the issue is Mylio related or file related, and how to ensure your images remain safe.

Corrupt Files

A corrupt file is an image, document, or another file type that is supported by Mylio but cannot be read because of an issue with the file itself. File corruption can happen for a variety of reasons, such as power failures, failed moves or saves, failed downloads, viruses or malware, or failing drives.

In cases where Mylio has detected a file is corrupted and can’t view or create a Thumbnail or Preview from the file, it is best to ensure that the file is actually unreadable outside of Mylio.

  1. Open Mylio and locate the corrupt file.
  2. Right-click on the image (Option+click on Mac) and select Show In Explorer or Show in Finder.
  3. Mylio will open the file in its original location on your computer. Double-click the file to open it.
  4. If the file is unable to be opened, the file is corrupt.

In most cases, a corrupt file can be safely deleted from your computer as no application can open it. However, you may wish to save the file for future reference or recovery at a later time. If you wish to save the corrupt file,  it is recommended that you move the file out of the folder you found it in and into a folder that Mylio is not referencing.

  Note:  Mylio is unable to help recover corrupt files.

Unsupport Files

Mylio supports a wide range of files including photos, documents, PDFs, videos, and more. And we’re constantly working to expand the types of files that can be imported into Mylio.

However, in some cases, you may import files into Mylio that cannot be read.

Unsupported files come in two types:

Unsupported Files That Mylio Can Import

Many times, Mylio can import an unsupported file and sync the unsupported file between your machines. This is especially true for RAW photos taken with newer, or much older, cameras. In these cases, Mylio will import the image but not be able to display it. The image will replicate between your machines and you can view the image outside of Mylio using File Explorer or Finder, or using a third-party application.

We strive to increase our camera support with every update. When we do add support for the unsupported file, Mylio will begin to display the image on all machines and create the needed Thumbnail and Preview automatically.

For a full list of cameras supported by Mylio, please see our RAW Camera Support list.

  Warning:  though unsupported files will not look like an image, it is important that you do not delete the file as this is your actual image file, it simply is not viewable by Mylio.

Unsupported Files That Mylio Cannot Import

In some cases, you may attempt to import a folder or file that is not supported by Mylio. When a file is fully not supported, the file will not be visible in Mylio and will not sync between your devices.

Furthermore, if unsupported files are within a Source Folder, Mylio may not be a 1:1 copy of your file system as we are unable to import the files within that folder.

Files that are wholly not supported by Mylio will not interfere with your Mylio experience. If the file type is later supported by Mylio the files will be imported automatically. Otherwise, the files will simply not be visible within Mylio.

For a full list of files types supported by Mylio, please see our File Type Support list.

  Note:  if a Source Folder is deleted from Mylio that contains items that can’t be imported, the imported content will be deleted from the File System and unsupported content will remain.
  Note:  if a folder is imported using the Copy command and “Delete Files After Import” is turned on, files that are not able to be imported will remain in their original location, not deleted.


Confirm Drag and Drop Action

When using Mylio you may inadvertently drag and drop an image or folder onto another folder. Because Mylio is continuously syncing, this means your photos will be rearranged on your other devices as well.

If this is something that happens frequently, you can toggle a setting with Mylio that will alert you when a drag and drop action has occurred.

This option can be toggled by following these steps:

  1. Open Mylio.
  2. Select Settings from the View menu.
  3. Select General.
  4. Toggle on Confirm Drag and Drop Action.

Protecting Media to Amazon Drive

Mylio allows you to easily protect your photos to the cloud by making Amazon Drive a Mylio Vault. Once this feature is enabled, any media within your Mylio Library will automatically be protected to Amazon Drive. If your device is lost, stolen, or broken you can retrieve all synced media from Amazon Drive and fully repopulate your Mylio Library – including photos, videos, files, metadata, albums, events, labels, and any other Mylio specific data. Amazon Drive can also be used to populate Mylio on computers that are not able to be synced peer-to-peer.

Once Amazon Drive has been added as a Vault it will be listed in the Devices section of the Dashboard. Unlike other Protection Devices (NAS and USB devices), protecting your files to Amazon Drive does not give you the ability to edit data within Amazon Drive for reflection in Mylio. This feature is designed solely as a tool for Mylio to communicate with and is not an alternative traditional uploader for Amazon Drive.

  Note:  Amazon Prime Photos must be uploaded unencrypted. 
  Note:  Amazon Drive is a subscription service. If your account expires, Amazon may delete photos from your drive.

Uploading Encrypted vs Unencrypted

Before deciding on an encryption method, it is important to understand that Mylio utilizes Amazon as a Vault for your files. Mylio does not preserve your file structure when uploading and changes should not be made to the uploaded files on the Amazon Drive website, even if uploaded unencrypted. This protection method is solely meant to protect your Mylio Library and not designed to give compatibility between the two services.

Uploading Encrypted

Mylio’s default behavior is to upload your photos as encrypted files. If your images are uploaded encrypted, Mylio will encrypt your files in a way that Amazon is not able to read these images, keeping your library fully secure. This ensures the highest level of protection as Mylio is the sole key to locking and unlocking your images.

Encrypted Amazon Drive protection uploads your files as “other files” and not “photos”, which means this option is not compatible with Amazon’s free Prime Photos and requires Amazon Drive. Amazon provides a free 5GB of Amazon Drive space that Mylio can utilize. Additional storage can be purchased from within your Amazon Drive account.

Mylio protects your images in the cloud with AES 256bit encryption. Only your Mylio account can be used to unencrypt these images.

Uploading Unencrypted

Mylio will upload your files directly to Amazon in full, original quality. These images will upload as their actual file-extension and be viewable by Amazon. Mylio will not be needed to view your images.

Unencrypted Amazon Drive protection is compatible with Amazon’s free Prime Photos. However, libraries with more than 5gb of non-photo files, including videos, may still run out of space. Additional storage can be purchased from within your Amazon Drive account.

Working With Amazon Drive in Mylio

Setting Up Amazon Drive

1. Open Mylio on a computer and open the Dashboard.

2. Select the plus sign in the top right of the Devices section of the Dashboard.

3. Select Amazon Cloud.

4. Mylio will display the Add Cloud Storage options. Here, you can choose if you wish to upload your files encrypted or unencrypted. If you wish to use Amazon Prime Photos, you must select unencrypted. Once decided, select Add Amazon Drive at the bottom of this dialog.

5. Sign in to your Amazon account.

6. Once signed in, Mylio will display Amazon Drive within the Dashboard as a Vault.

Restoring Mylio from Amazon

In some cases, you may need to restore your Mylio Library from Amazon Drive. This may happen if your device is lost, stolen, broken, or if you are starting Mylio on a remote device that cannot connect to another device via a peer-to-peer connection.

  1. Open and sign in to the Mylio account previously associated with Amazon Drive.
  2. Open the Dashboard and ensure Amazon Drive is listed as a Vault.
  3. Mylio will automatically begin to download your Mylio catalog and library to the new device.
      Note:  this process may take time. To speed up syncing connect to another device via a peer-to-peer connection that has your Mylio Library).

Unregistering Amazon

If you wish to unregister Amazon Drive as a location that Mylio can sync to, you can do so from the service’s sync preferences. By unregistering Amazon Drive, you will prevent Mylio from protecting any new media to Amazon Drive. Media currently on Amazon Drive will not be removed from the service.

  Warning:  if Amazon Drive is unregistered and then set up again your library will need to fully resync to the service.
  1. Open Mylio’s Dashboard and navigate to the Devices section.
  2. Select Amazon Drive to open the Device Settings menu.
  3. Select Unregister Device.
  4. Confirm that you would like to unregister the device by typing in your Mylio password.

Known Issue: Mylio and macOS Storage Optimization

macOS Sierra and newer include an option that will automatically optimize storage on your local drive by removing data and storing it in iCloud. When this happens, Mylio loses access to the original file, resulting in Mylio not seeing the photo is there and being removed from Mylio. The removal of this file from Mylio is then synced to your protected devices and other devices on your account. This results in a situation where Mylio does not display images that you may expect to see, or you are able to see in Finder.

At this time, it is recommended that you do not use Apple’s Storage Optimization features in conjunction with Mylio as it can cause apparent data loss (though not actual data loss as your photos are in iCloud). We are investigating resolutions for this in future versions.

To turn this feature off:

  1. Open the Apple menu on your computer running macOS Sierra or newer.
  2. Navigate to System Preferences, then iCloud.
  3. Select Options next to iCloud Drive.
  4. Disable Optimize Mac Storage at the bottom.

Error Message: “Failed to get access to path.”

In some cases, Mylio may display that it is unable to get access to a specific file path. This happens when Mylio does not have permission to access a set of files or folder that it is referencing. Generally, this issue is indicative of a file or folder that is locked or read-only.

If you receive this error message, please ensure that your device’s permissions are in good standing using the links below:

Additionally, this error may be received if Mylio is unable to locate, read or write to the Generated Images bundle. This bundle holds thumbnails and previews created by Mylio and is required to be a part of your library. If this file was moved purposefully, it should be moved back to its original location and steps to move your entire library should be taken if needed.

If the Generated Images bundle was deleted and your device’s library is stored in the default location, simply selecting Create New when launching Mylio will re-create the Generated Images bundle in the correct location.
