Mylio Photos

External drives allow for many different configurations that may work in some situations but not others. This guide will walk you through the basics of reformatting a drive and how to best format it for your setup.

<b>NOTE:</b> Mylio Photos is not compatible with applications for macOS or Windows that allow for non-natively supported drives to be read/written to by unsupported operating systems.

Drives can be formatted in two primary different formats: NTFS and APFS. When choosing the right format for your hard drive, it is possible that you are formatting the drive to work with one specific operating system.

NTFS drives can only be read and written to by Windows computers.

APFS drives can only be read and written to by Mac computers.

- NTFS drives can only be read and written to by Windows computers.
- APFS drives can only be read and written to by Mac computers.

If you are formatting a drive to be used solely by a Windows or Mac machine, choosing a traditional NTFS or APFS format is ideal. These formats offer high stability and features that keep data secure.

If you are interested in using a drive on both Windows and macOS, you may be interested in using a format known as ExFAT. ExFAT allows a drive to be read and written to in both environments but is generally seen as less stable and missing some features that both NTFS and APFS offer. Nevertheless, for basic file storage, ExFAT is a great option.

<b>WARNING:</b> Formatting a drive will completely erase its contents.
