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 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) 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 continue to display any edits or information associated with the photo. This is because Mylio also saves the edits to the Mylio Catalog as Mylio-specific information. However, viewing these photos in external editors (such as Lightroom) would show the original, unedited version.
Some file formats, such a JPG, can hold edit information, including ratings, flags, and labels, within the file itself. This can be done by ‘Saving Metadata to File’. Saving the metadata can easily be done by selecting the image and navigating to the ‘Photo’ Menu and “Save Metadata to File”. This will not remove the XMP, but it will save the XMP information to the file itself.
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 easily within Mylio by exporting the image.
