title: MKS cleaning projects of not useful files
body: <p>I am using MKS on mi work daily, and I work with a very big repository thata contains a lot of projects, with a very colorful structure. On my department, we want to improve this project erasing all the optional files (.suo, .pdb, .txt, bin folders, obj folders, and more).
  I know, that I can configure the files/folders that I want that the MKS ignore</p>
  
  <p>it is explained here(<a href="https://stackoverflow.com/questions/4377774/mks-equvilant-to-svnignore">MKS/ PTC Integrity Source equivalent to svn:ignore</a>)
   but, 
  is there any way to make a selective erase of all these kind of files without having to check out all the files, deleting all the files I want to, and check in again these changes?</p>
