DeleteFileVersion Method

Deletes a file version.

Syntax

backblazeb2.deleteFileVersion(fileId, [callback])

Callback

The 'callback' parameter specifies a function which will be called when the operation completes (or an error is encountered). If the 'callback' parameter is not specified, then the method will block and will not return until the operation completes (or an error is encountered).

The callback for this method is defined as:

function(err){ }

'err' is the error that occurred. If there was no error, then 'err' is 'null'.

'err' has 2 properties which hold detailed information:

err.code
err.message

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.
