Thanks for putting out such useful programs for free... I must say that running a combo of CCleaner and defraggler helps maintain computers with the greatest of ease. There are a lot of great suggestions throughout the suggestions forum, however I've failed to see the suggestion that I would most like to see.... My suggestion: Include a switch in the commandline df.exe to search for and defrag all fragmented files only. Currently a "df c:" will defrag the drive and, I assume, free space because it takes significanlty longer to defrag that way than using the gui to defrag files only. I realize that I could specify multiple folders for df to defrag, but a feature to simply defrag all fragmented files would be awesome. Keep up the great work!
