You have your user profiles on a super-small drive? For that matter, the C drive?!? Time to move those. This has nothing to do with VirtualBox.
Doesn't it? Doesn't it though?
Most, if not all, Windows-native applications will store related data some place standard like my documents. Storing potentially large files in some subfolder under %USERPROFILE% is perhaps standard on unix/linux type OSes because it is the "home" directory but in Windows it is entirely non-standard and every bit annoying. Perhaps "beginners" to VMs (but other-wise "enthusiast" types) would be panicked when they're suddenly getting "low space" notices for their C: drive. Or I could be way off.
Applications do store user-specific information there (like cache or whatever) but not actual data files like multiple 4gig files...I've noticed this is common with programs ported from linux (I use jedit all the time at work).
And it's not "super-small" (120 gig IDE drive) but I like to keep the OS stuff as isolated from the data stuff as possible. I did back ups with Ghost 8 at one point so it was already imperative to keep that OS drive as small as possible so I didn't need that much space for backup (then I can restore just the OS and not worry about my data).
Of course there's some people using 80 gig solid state drives who still have their profile on C: so this would be something to note.
On a side note I'm weird since I don't care how fast the machine boots as long it's FAST when it's done booting (my sig rig fills that bill). Thus I'm not buying a sold state until they're a reasonable capacity for ~$90 Edited by subassy - 3/11/11 at 8:22pm
