Remarks

The Replace method replaces the contents of a specified file with the contents of another file. It also creates a backup of the file that was replaced.

If the sourceFileName and destinationFileName are on different volumes, this method raises an exception. If the destinationBackupFileName is on a different volume from the source file, the backup file will be deleted.

Pass null to the destinationBackupFileName parameter if you don't want to create a backup of the file being replaced.

If the destinationBackupFileName already exists, it's replaced with the contents of the destinationFileName file.
