Ok I have got some pretty good help from everyone on here so far so lets see if anyone can figure this one out. I have a WD Passport 320GB External Drive and it shows 298GB Available. Ok fine. Now it says I still have 185GB used and 112GB free. But here is the problem, I can not copy any more files to it because it has an error that says "Cannot copy *****.*** There is not enough disk space. Delete one or more file to free disk space, and then try again. To free up space on this drive by deleting old or unnecessary files, click Disk Cleanup." I can not figure out how I am out of disk space. I should have pleant enough to copy whatever I want to. Any help would be appreciated. Thanks.
