I did a Full Defrag on my computer. When I click File List, I get a bunch of files. Should I check them all and press Defrag Checked or leave them alone? Please tell me the pros and cons of doing that, thanks! EDIT: I checked all the files and click Defrag Checked. I got a popup saying: "Defrag Aborted. Some files were not defragmented. This operation cannot be done."
