You're probably right about the Avira thing. I'll run a scan tonight and take a look in the morning.

My wife and I are/were online teachers for the past 6 years. Email is the way we did everything. I am up over 3000 for just this semester! I try to manage the attachments, but likely didn't do well enough.

On this machine using XP, we have two accounts. I just did a quick look at each to determine amount of space used in each account. After transferring, my side is down to 12.4 GB, her side is at 6 GB and a shared docs folder is at 1 GB. I then looked at the installed programs under 'add/remove programs' (which takes a really long time to open, btw) and the largest here is 400 MB goes down from there. There are some that we could get rid of, but nothing of substantial size. So, I can't really tell where all that used hard drive space is going.

Thanks for the assistance so far.
