Today I had decided to clean-up my Hard drive (into Windows XP)
After I have deleted a lot of files (8 GO) I found a folder named
C:\System Volume Information containing 500 MO of datas (copies of a big numbers of exe, INI, dll...) and I don't know what is the goal of this folder and if I can delete it.

If someone know the goal of this folder, please provide your knowledge with me.Thanks
