Alternative to windirstat?

We’ve used windirstat for a long time when investigating why server or desktop hard drives suddenly fill up. It’s a very quick way of finding out who has just synched their ipod to the server network share.  Earlier this week though we found that it was reporting a drive had 40gb used out of 115gb yet the OS was showing 2gb free. Obviously this is a rather large discrepency and was the second time we’d had windirstat not match the information that Windows was reporting.  After a bit of digging around, I checked the volume shadow copy settings, set it back to a more reasonable 10gb instead of 99.2% of the disk and our free space went back to about 70gb in windows – now matching what windirstat was reporting.

So it looks like windirstat does not take into account files such as the VSS cache location.

So we’re looking around for an alternative – I’d really like it to be a standalone application – if you know of anything then please add something in the comments and I’ll add a new post with my preferred solution.


windirstat is a great utility to work out how much disk space each folder/file is using. When you get down to the file level it will show you in a graphical format as the larger the file, the larger the colour block on display. Using this utility it was very easy to find out where the 12gb of disk space had suddenly gone on a server – it quickly showed me that a particular user had a large docs & settings and within that was the desktop and on the desktop were 2 6gb .tmp files!
