Everytime a dbpro exe runs it creates a folder in your temp folder called dbpdata. It extracts dlls and attached media into the folder. Sometimes it doesn't delete the folder when the program exits so you can end up with lots and lots of them and they can be several Mb each.
If you have no dbpro exe running it is save to go to your temp dir and just delete all of them.
The location of your temp dir varies between windows versions.
for win9x
c:\windows\temp
for win2k/xp
C:\Documents and Settings\[USER NAME]\Local Settings\Temp
That would only account for a small ammount, I don't know why it is eating up so much disk space.
