DeleteFileVersion Method
Deletes a file version.
Syntax
backblazeb2control.DeleteFileVersion FileId
Remarks
This method deletes the file version specified by FileId, regardless of whether said version is an actual file or a hide marker
If the most recent version of a file is deleted, and older versions of the file exist, then the most recent older version will become the "current" version. If said version is a hide marker, then the file will become "hidden"; refer to HideFile for more information.
The currently-authenticated application key must have the deleteFiles capability to call this method successfully, otherwise the server will return an error. Refer to the AccountCapabilities property for more information.
