What does the Apple .aae file extension stand for? I presume it stands for something, as file extensions usually do.
Arbitrary Apple Extension is my best guess, but Google offers no results.
An AAE file contains edits made to an image using the Photos app on an iOS device. It is used to transfer non-destructive edits a user has made to .JPG images in iOS to the macOS system. AAE files can be found accompanying the images for which they contain edits.
An .AAE file is simply the edits that have been made to an existing photo on an Apple device. An AAE file can be deleted without erasing the actual photo, but you will lose all edits you have made to the file. The edit data is saved in an XML format that can be easily viewed in a text editor like Notepad.
