Vista disk space filter: What's eating 190 GB on my computer?

So, my C drive is 229 GB. Windows Vista tells me I have 5-ish GB free (screengrab). When I run a program to see how I'm using the disk space (WinDirStat), it appears as though I'm only using 33 GB (screengrab). Any ideas what is going on here?

Try running scandisk. Right click on your hard drive, Properties/Tools/Scandisk.

Free space count is probably wrong.

chkdsk /f c:
and reboot.

Best answer: The 'shadow copy' 'feature' might be eating it all.

Response by poster: Chkdsk / scandisk doesn't solve it.

I depend on the Sequoia View program to see what's eating space on my drives. I use Win2K so I'm not sure if this works under Vista or not, but it might be worth trying.

WinDitStat is an open source program that does what Sequoia View does.

Best answer: Shadow copy it was (using 191 GB of space). This page explained how to find out how big it is and how to limit its space.

Volume Shadow Copy has been around since XP and Server 2003. It's analogous function is Time Machine in OSX. I don't know what happened to gavia but it's unexpected behaviour, not by design. In Vista, shadow copy is controlled in System Properties under the System Protection tab. Individual files are controlled by the Previous Versions tab on any file property sheet.
