Working with Documents
The program saves documents in its own format. Document files have the "amdn" file name extension. To search for your documents, type "amdn" in the search box of Spotlight.
To save the current document, select File > Save… or File > Save As… menu command. The latter appears in the menu when you hold down the Alt key.
To find out the location of the current document on disk, right-click on the document's name in the title bar of the main window.
The operating system automatically saves versions of modified documents. Due to this feature, you don't need to save documents frequently during your work. Since the auto save feature has limitations, it is recommended that you periodically save your document manually. To find and restore any of saved versions, select File > Revert To > Browse All Versions….
In the program Preferences, you can choose how often the program automatically saves a copy of your document. This function is useful for avoiding data loss in case of a power shortage or software problems.
If you have an account at iCloud, you can save your documents to your iCloud storage. The iCloud option is located in the Save and Save As dialogs.
