Hi Sujay can post a screenshot of the folders,
C:/RECYCLER Folder
C://RECYCLER is basically a location where a users deleted files are stored. After a user empties their Recycle Bin the data will stay in the RECYCLER location. This could be viewed as a kind of hidden back-up for deleted files (99.9% of users don't know about it) or back door to track a user if ever needed. I would imagine its purpose is in the event a user deleted a critical system file that needed to be recovered.

System Volume Information Folder

It's actually a part of System Restore; the tool that allows you to set points in time to roll back your computer. The System Volume Information folder is where XP stores these points and associated information that makes them accessible. If you have System Restore enabled but don't see this folder, go into [Tools] [Folder Options] [View] and click the radio button next to [Show Hidden Files and Folders] and it will be visible.
