Doing something wrong in OSX mail, 170gb gobbled up

[GGD]

Run Disk Inventory X to see what is using the space. Hundreds of 32MB files doesn't add up to 170GB, so maybe there is some sort of mail issue, but it's also possible that there is a bigger issue someplace else.

Also, on those strange files, what are the creation dates? Were they all just recently created during the time all of the disk space got consumed.
