After I defragmented my c drive, the report stated that a certain AVI file could not be defragmented. The file size was 7.2 GB. I figured that I would delete that file and get a lot more free space on my hard drive. However, this file cannot be found anywhere on my computer. Search doesn’t find it. When I tried going directly to the path of the file which was stated in the defragment report, it would not let me access that path. The beginning of the path was c:\userdata, but access was denied. In addition, the properties stated ‘folder is empty’. Can someone please explain what is going on here?
