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.

Error Handling (C++)

This method returns a Boolean value; after it returns, call the GetLastErrorCode() method to obtain its result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message.
