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

[James T.19]

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.

Thanks you for having shed a light on this.

If I am a regular Dropbox user and not a developer using any of the versions among basic, pro or business, what could I do with these file and folders IDs?

Is there any feature of either the desktop application or the web interface which uses these object  IDs?

Is it mentioned in any of the menus in either the application or the web?

Thanks in advance,

Aldo

Hi Aldo, file IDs aren't really exposed to users anywhere. They're intended as an aid for developers in the implementation of apps.

Thanks Gregory.
