I have a number of duplicated file names preceded with "._" which seem to do nothing but fill up my file lists with files that don't open. The first time I noticed them was in MPlayer. There were only a few and it was not not a big deal. In Media Box however there are WAY too many.

None of them open nor can they be found by the search tool.

Are they junk that can be removed?

If so I'm guessing it would be via the terminal which I'm not afraid to use, but lack the expertise to know the commands find and remove them.

I tried this: find / -name '._'
to no avail.
