Updates the used file count and storage size for a virtual folder. Use mode to add the supplied values to current usage or reset usage to the supplied values; omitted values default to zero, with different effects depending on the mode.
Quota usage values to add or set. If used_quota_files or used_quota_size is omitted, it defaults to zero; in add mode the omitted value leaves that usage unchanged, while in reset mode it sets that usage to zero.
A 400 is returned for an invalid request, a 401 when authentication is missing or invalid, and a 403 when the authenticated user is not permitted to update quota usage. A 404 is returned when the folder does not exist, a 409 when the update conflicts with the folder's current state, and a 500 when the server encounters an internal error. The name path parameter must identify the folder to update.
