Where are the eM client mail folders stored?

I know they are somewhere in my C: drive, however, I cannot see past the last folder they are stored. Please help.
I created tasks off of some mail pieces, and would like to attach them to the task but cannot retrieve the original. I cannot copy and paste and have not been able to find the folder either thru a search or looking at the program folder.

Please help

All your mails are saved in one database folder so am not sure if that is what you are looking for.
Database location:
C:\Users%Current User%\AppData\Roaming\eM Client (Vista/Win7)
C:\Documents and Settings%Current User%\Application Data\eM Client (XP)
