Dcm files visible on source drive

Hi, I had some trouble with my Windows 7 computer that I think may have been caused by the Anywhere Backup software.  I fixed the problem, but one of the side effects was that the dcm files are visible on my source drive.  I tried contacting WD Support, but after going back and forth with them, their final response was that I should resinstall Windows 7 on my computer.

After laughing, I thought I would contact this forum to see if anyone has any better ideas than reinstalling Windows 7. I would love it if there was a way to hide dcm files en masse instead of one at a time.

The other two computers I back up data from don’t have this problem.  Thanks!
