What is .ANNOT file extension?
File created by Adobe Digital Editions (ADE), an ePublication reader; may contain bookmarks, highlights, and text notes for an .EPUB file; commonly referenced by a corresponding manifest.xml file; used for saving and loading user-generated annotations.
In Windows, ANNOT files are saved to the \Digital Editions\Annotations\ directory within the user's Documents directory. For Mac OS X, they are saved to the [user]/My Documents/Digital Editions/Annotations/ directory. ANNOT files often use the title of the ePublication as their filename prefix.
Since ANNOT files use XML formatting, you can view them with a text editor.
