    Used disk space discrepancy

    My machine running Vista Business shows 157 GB used on the C drive, but I see no more than 70 GB by adding up all the files and folders including hidden and system ones. I installed on a handful of applications on this machine. I am wondering if anyone could provide some hint to help sovle this puzzle.

    Thanks in advance!

    Hi ZS and welcome

    It can be a lot ot things but I can tell you how to find out. there is a 3rd party app called treesize pro its here Welcome to JAM Software. the trial is free and it will see every file and folder including backups, etc.

    Thanks a lot, Ken.

    I installed TreeSize as you suggested and found the culprit is "System Volume Information" which is shown to be 0 bytes in Windows Explorer, but about 100 GB n TreeSize.

    Could shed some light on this folder?
