FileExists Method

Checks whether a vault item exists.

Syntax

cbmemdrive.fileExists(fileName, [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, data){ }

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

'data' is the value returned by the method.

'err' has 2 properties which hold detailed information:

err.code
err.message

Remarks

This method checks whether a vault item (file, directory, symbolic link, or alternate stream) with the specified FileName exists in the vault. If the specified vault item exists, this method returns true; otherwise it returns false.

The value passed for FileName must be a vault-local absolute path.

Note: This method can only be called when Active is true.
