I recently copied all of my ripped movies (DVD’s) from my iMac to an WD Elements external hard drive. I then connected the hard drive to my Samsung TV. As all of my files were ripped to .m4v format my TV wouldn’t recognise them. A simple fix, which worked, was to use NameChanger to simply change the file extension of all my movies to .mp4. My TV recognises and plays the files fine BUT I now have some duplicate files which start with ._ before the name, for example: ( ._GOODFELLAS.mp4 ). These duplicate files do not play and annoyingly appear at the top of the list. When I go back and connect the hard drive to my iMac to try and delete these ._ files, they do not appear. I have already tried showing hidden files option on my iMac but they still do not appear. I have also erased the hard drive and copied all my files back but the ._ files still appear when connected to my Samsung TV.
Any ideas on how to find and delete these pointless duplicate files from my hard drive?
Thanks in advance.
