Working with Documents
The app saves documents automatically when you open the document browser from the main window, and also when you switch to another app.
The app stores documents in its own format. Document files have the "amdc" file name extension. The same format is used on all platforms that are supported by the app. Documents in this format are compressed. There is another format "amdn" that is used for storing documents without compression. To save your document in this format, bring up the Export panel and choose the AMDN format.
