RECYCLER and SYSTEM VOLUME INFORMATION

RECYCLER:It is the folder that any files you place in the recycle bin are placed. You need to make unhidden this first by "attrib RECYCLER -r -a -s -h" and then simply delete the same.


SYSTEM VOLUME INFORMATION:It is the folder where windows system restore files are located. If you do not want to use this folder then disable System Restore.

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.

At a Command Prompt issue:rd /s /q c:\recycler - (Use at your own risk) You want also to check permissions on this folder.

C:/System Volume Information Folder

If you've done much wandering around in Windows Explorer you might have noticed a folder called System Volume Information and wondered what purpose it serves. 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.

How to operate/remove System Volume Information folder?
Access is denied to this folder by default. If you feel that there is a virus inside this folder, the to fix:

This will delete all contents inside System Volume Information folder restore points including viruses backed up there. Remeber to turn system restore back on, so that it will recreate with virus free new system restore info.

::::Note >> Both Recycler and _Restore (System Volume Information) are system folders. Their contents can be deleted but they will recreate.

There is free utility "Unlocker", it can help. Here is link:

And If you are using winXP, you can remove System Volume Information by disabling system restore: right click "My computer" -> properties ->System restore
**********************************************************************************
Look If your pc is virus free and you are sure that these folders are not virus then you can

Go to services.msc and disable system restore there and reboot. It will delete system volume information folder which is used to create restore points by windows.
**********************************************************************************
These two folders might contains most of the virus like...

w32.gammia
w32.infostealer

In one organisation where we have installed SEP, we found it, it was very easy to go and manually delete all files inside both folders, instead of SEP to scan and remove viruses. Couple of file does not get removed, ignore them.

This will reduce the scan time, and SEP will remove virus from the files which can not be deleted, if virus are present.
