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 many System Volume Information folders your computer has and where they are located depends on the settings you've selected for System Restore. For an overview of System Restore and how these interactions apply, click here

Using CACLS with Windows XP Home Edition Using the NTFS File System

In Windows XP Home Edition with the NTFS file system, it's necessary to take a different approach since Simple File Sharing does not allow modifying the Access Control Lists (ACL's). The result is the same, but you use the Cacls command-line tool to modify file or folder access control lists (ACL's).

Click [Start] [Run] type cmd and click [OK].
Navigate to the root folder of the partition where the System Volume Information folder you want to access is located.
Type cacls ":\System Volume Information" /E /G <username>:F and press ENTER
Note: In this instance, make sure you type the quotation marks as shown in the line above.
Double-click the System Volume Information folder to open.

To remove permissions, type cacls ":\System Volume Information" /E /R <username> at the command prompt to remove all permissions for the user.

Using Safe Mode To Bypass Simple File Sharing

In situations where Simple File Sharing is being used it's easier to start the computer in Safe Mode because Simple File Sharing is off by default when XP is booted into Safe Mode. This is exactly the same routine that is detailed above in the "Windows XP Professional using the NTFS File System on a Workgroup or Standalone Computer" section

In Windows Explorer click [Tools] [Folder Options]
Click the [View] tab, click [Show Hidden Files and Folders]
Clear [Hide protected operating system files (Recommended)] check box.
Click [Yes] on the change confirmation box and click [OK] to exit.
Right-click the System Volume Information folder in the root folder.
Click [Properties] and select the [Security] tab. Click [Add]
Enter the name of the user you are allowing access to the folder.
Click [OK], and then click [OK].
Double-click the System Volume Information folder to open

In all likelihood you'll never have any reason to access the System Volume Information folder other than to satisfy your own curiosity as to what it contains, but you never know; having that little piece of info tucked away may prove invaluable one day.
