Dissection results - can folders be deleted?

After IT re-installed SW2008 sp3.1 on my workstation, the task scheduler was enabled and has been crashing each night now for a week. ... turns out the system drive is out of space and the dissection folders (11,546 of them) have expanded to consume 11.2GB of the disk space.

Big question I can't find an answer to:

Can I safely delete those dissection folders? These are the folders listed under the user application data folder and named with braces {} surrounding some kind of code number/name for the folders.

Thanks all.

(edit:

Just found out - apparently it IS safe to delete these folders. If anything untoward results, I'll be sure to follow up.
