title: Eclipse made files empty
body: <p>Just about an hour ago, I decided to switch my workspace folder in eclipse. So I created a new folder, moved all project folders to the new workspace folder and set this folder as the workspace folder in eclipse. Obviously, I had to re-import the projects, so I clicked import, selected the project and unchecked the copy to workspace checkbox because they were already in my workspace, but this gave me an error. So I tried again now checking the copy to workspace checkbox (I thought it could do no harm) and I didn't get an error. However, when my workspace loaded I got a lot of error and I noticed that eclipse had emptied all my project files! All files were still there, but all the data was gone: the files were 0 bytes.
  I do have a back-up from most of my projects, but there's one project I hadn't backed up yet, so my question is: is there any way to recover the projects?</p>
