Windows 7 - ~8-9 GB used in C:\System Volume Information\ ?

I was defragging with defraggler and i noticed that there were a few defragmented files in System Volume Information but they were huge files which added to about 8gb. It could be more as only the fragmented files add to 8gb.

I was wondering where these files came from? They have long, random letter/number names and range from 200mb - 3gb each

Before my factory settings reset, i used to have only 1 huge file in system volume information which was ~2gb.

is it okay if i delete these files

thanks

They are system restore points.

System Restore

You can safely delete all of them but the most recent one to get the space back if you like, but be aware that you won't have those points to go back to if you ever need to, except the most recent one made. They will be made again after a while, which you can then repeat if you want. Or you can just leave them be.

You can also change how much or how little space system restore will take up. Or just leave it like it is.

dear mod,i am having same problem,is there any way dealing with this problem in windows XP, i would be very thankful to u for ur kind help.

You could start out with this Technet article that explains System Restore in XP.

Windows XP System Restore

To change the amount of hard drive space that's set aside for restore points, click Start > All Programs > Accessories > System Tools > System Restore and click on the System Restore Settings link. Select the drive for which you want to change the System Restore settings, and press the Settings button. You can change the amount of disk space used by System Restore on the selected drive, or turn System Restore monitoring off for the selected drive.

Hope this helps.
