All my LW shared files disappeared
 

My computer ran Disk Cleanup a couple days ago, and when I went back into LimeWire today, it showed I had no files to share in my library. All my files are saved under the default setting, but I didn't think they would be considered temporary files (which is what the cleanup deleted). Is there any way to retrieve them? Or, if not, how about some way to store them in a place that won't be affected by the Windows disk cleanup.
