			* Works for text, binary and imported resources * Allows better clean up of duplicate files. TODO (future PRs): * Use this API for assigning new UIDs to copied files. * Use this API for UID conflict on FS scanning (if more than one file has the same UID, the newer one(s) should get assigned a different UID).
