C-drive has excessive used space

[santojmezzaroba]

According to Power Quest-Advanced View-Backup History, there is no record of Me making a backup. I believe I attempted to backup using (C:\) drive as the designated folder. That is why I had such a large hard drive usage number. I uninstalled Drive Image and after I reinstalled it the hard drive usage dropped to
38GB from 120GB. That number is probably pretty realistic.
The kma. file with 1782 songs is still on the hard drive. I am not having much success opening it to Hoster. Help if You can!
In Power Quest-Advanced View-Drives tab I show two drives. The first is My
Local Drive (C:\). I can not remember creating the second and according to
Power Quest, I never created any drive. I believe it came with the unit. the name is (x:\) but the x is very small and is up high. I imagine it is a back up of some kind.
My lack of knowledge has already caused me a lot of problems so I am trying to use caution.
