I don't mean to nitpick, Tom, but is this really your plan?

So apparently there’s a hidden folder in Windows called “system volume information” which stores information related to restoring the system if needed. But here’s the thing: it does not come with any default limit on how big it can get. So my year-old 120-gig hard drive, on which I’d put 30 gigs of stuff, was showing that it only had a few megs of space every couple of days. And this folder is, let me repeat, hidden and admin-only, which meant that the disk analysis utilities I was using didn’t see it/couldn’t tell how big it was! TreeSize Free did tell me that it had been denied access to several folders, including system volume information, and through the power of xkcd-style tech support (that is, I googled the term) I found out that I should use the command line prompt in administrator mode to determine its size. Answer: 80 gigs. A few commands later, I suddenly have 80 gigs free again. Every step of this has been resoundingly stupid: stupid that there’s no programmed constraint on the size of this folder; stupid that it’s then hidden; stupid that it can only be fixed from the command line. Windows tablet PC, I wish I knew how to quit you.
