space sucker 4000

Hi, people who are smarter than me!(everyone)

TL;DR version
Are there any good programs that can show files that are being added to my computer, maliciously or not?

My computer seems to reach critically low disk space often. Every time I make space it seems to be filled up rather fast, but I don't beleive I am the one adding the files.

Usually, when space on a windows XP/2000 computer, it's because you've got "offline files" enabled.  I can't remember exactly where it stores this, but it's somewhere in the windows directory.

What it is is that your computer is mirroring all the files on some network share onto your local drive, such that you can access them when you're not on the network.  This is a stupid feature, because large files are usually stored on shares so that they don't take up space locally, and small files that you want to store remotely tend to be updated often, such that if you try to update them in your cache, your version will be overwritten later.

I guess they were just trying to avoid their tech support department having to explain to people that you need to be on your network to be able to access certain files.

I'm not at my XP machine right now, but it's easy enough to disable.  It's somewhere in the options for explorer.

Once you've done that, reboot and find the folder under C:\Windows that's taking up a ton of space and delete it (if it doesn't automatically, I seem to remember it not, but it's been a long time since I've used windows)
