Hi Bodgan,

I use WinXP Home Edition and the Windows Explorer does not allow renaming of file to filenames starting with a dot. However, the file can be renamed using the command prompt.

Start the command prompt:
"Start Menu -> Programs -> Accessories -> Command Prompt"
OR, type cmd on the "Start Menu -> Run window", and press enter.
Change directory to your exiftool directory and use the following command:

Hope this helps.
