With even a simple 33.6 modem, it isn't hard to fill up 1.2GB of space. Once you're wired into the Net, it's just a short period of time before your drive is filled with a ton of games, apps, utilities, and whatever else you can get nowadays.

And when you're finally out of space, what do you do? You probably hit the obvious spots: the download directory, Program Files, and wipe out your Temporary Files directories. And still, you're dangerously low on space.

There exist hundreds of disk space watchers and pie-chart analysts. Sure, they can tell you what your hard drive space looks like and what directories take up the most space. But can they tell you where all that free space you had last week went?

Which directories have grown since this morning, in what directories have you actually gained space from cleaning, and what directories haven't changed at all?

Drive Doppler gives you all these answers. The method is simple: take digital snapshots of your hard drive file distribution now, do your usual computer-thing, then take another snapshot and compare the two.

Through comparison, you can see where all your once-ample hard drive space has been sucked into! Make the $300 you paid for that super-huge hard drive go that extra mile. Or just squeeze months or even years out of that old 1.2GB drive.
