It seems that this tool hasn't been updated since 2011.
Note: For the users of Mac OS X 10.6 (Snow Leopard), or later, .DS_Store enabler/disabler has been replaced by CleanUp smb mess.
CleanUp smb mess cleans quickly and easly FAT/FAT32 drives, pendrives, SD memories for mobiles and cameras, SMB/CIFS Samba shares (Windows and Linux) from ".DS_Store" and "._*" files, and other invisibles files a Mac lefts behind.
