What are the properties of the File ID in API v2?

Does the File ID change when any byte of the file changes? Or would that be a different revision of the same file? What events cause a new File ID to be issued?

Changing the contents of a file doesn't change the file ID, but does changes change the rev. That is, a file ID identifies a file, even across revisions, but the rev identifies a specific revision of a file.

Likewise, if you delete and restore a file, or move a file, the ID won't change, but the rev will.

If you make a copy of a file, the new copy will have a different ID and a different rev than the original.
