I don't think deleting individual files is a good idea. You could have one project folder that has files in it with different time stamps, so you could potentially just be deleting some files from a project folder. Also, you would have the projects.xml file that contains the list of open project in Studio - you can either delete this file and then Studio creates a new, empty one or not delete it. I don't know of a easy way to just delete some entries from it so that you synchronize that with whatever files you are deleting. So I think this approach is risky. You won't lose data, but you may have your users report errors in Studio.
