Understanding XMP Files

XMP files (extensible metadata platform) are an industry-standard format for holding additional metadata about your files. Mylio utilizes XMP files to efficiently move edit and file information between your devices. Mylio may create an XMP file for an image for a variety of reasons, including…

  • Importing photos with edit information already associated with it.
  • Adding keywords or other metadata to a photo upon import.
  • Editing a photo.
  • Labeling, rating, adding people, adding a location, or flagging a photo.

XMP files are responsible for recording data (in conjunction with your Mylio Library). associated with your photo. For instance, adjusting the contrast of a photo from within Mylio will not change the original image, but instead, write the contrast change to the XMP file. When viewing the file in Mylio (or other popular photo editing applications such as Lightroom Classic) the original, unedited photo is viewed while the XMP information is applied to that image.

If XMP files are removed from your file system, Mylio will no longer display any edits associated with the photo.

Saving Metadata To Original File

Some file formats, such a JPG, can hold edit information, including ratings, flags, and labels, within the file itself. This can be done by using Mylio’s Saving Metadata to File feature. Saving the metadata can easily be done by:

  1. Select the photo or photo(s) you wish to save the metadata to file for.
  2. Navigate to the Photo menu along the top, then select Save Metadata to File.
  3. Mylio will apply changes previously in the XMP file to the image file itself.
      Note:   This will not remove the XMP file.

In some instances, you may wish to save your edits onto your original image to view outside of Mylio. This is popular when emailing a photo or uploaded it to a printing service. This can be done in Mylio by exporting the image.
