System Volume Information? Server 2003?
So, I manage several VMs which I inherited from other QA department staff. They've been handed down from employee to employee for years, and as such, a lot of them have C:\ partitions which are too small. 6GB is just enough space to get a day or two of testing in before...
"your C drive is running out of space!"
And who do you suppose is the culprit?
The System Volume Information folder. Word around the internet is if you turn off system restore, that will fix it. But Windows Server 2003 does not use system restore.
So what is in that folder?
Raymond Chen over at Old New Thing
This guy covers it pretty well. Thanks man!
Now, if you're just trying to clear up some space, and aren't afraid to wreck things, well, you can go into the indexing service and delete the 'System' catalog.
Right-click on 'my computer', 'manage'. Under 'services and applications' is 'indexing service'.
Click on the name 'indexing service', and stop the entire service. Then, in the right-hand pane, click on the name 'System' (if it is indeed hogging a bunch of drive space, you'll see a rather large number after it), and delete it. I'm not an admin, so I will assure you: I have NO idea what this will do to your server. So if you need to know before you let that rip, well, perhaps you can research that out yourself.
I was told 'nothing should happen', but, just keep in mind that I am a QA guy and not an MCSE.
