System Volume Information Folder in USB?

I tried to format my 2GB USB drive in NTFS Format in WINDOWS XP. When i format the drive, it was formatted successfully, but inside the formatted drive one of the folder is created named as "System Volume Information". I tried to delete the folder, it says "Access Denied" also remove my USB drive safely but it show and error like "the Generic Volume is used in another program...". why it will happens, the folder "System Volume Information" is a virus?.. how can i overcome this problem... reply me as soon as possible.. thanks to all...

It's not a virus.

It's a system folder present on most NTFS volumes and is used primarily for system restore points (this folder is where they're saved to). It's intentionally set up so you can't simply delete it. To do that, you'll have to give yourself ownership of the folder and then assign yourself full access permissions.

If this folder bothers you, you might format your USB stick as FAT32 instead.

Thanks for your reply, why this (system volume information) folder will arise?.. Just now i format my USB drive in another Windows xp system, i can't get this folder.

Just rename the folder, it should disappear
