substituting c: with your drive letter. If it asks to schedule at rebbot, say yes, then reboot. This may not fix your folder, but should fix minor problems on the drive and help prevent future corrupt files.
If the file you are looking for resided on some bad sectors then chkdsk should have tried to move the data if possible and also mark those sectors as bad so that no future writes to the drive are made to those sectors.
Unfortunately there probably wasn't enough of your file left to fix it.
