I'm running out of internal storage space, and i don't want it to sync with my accounts later and move my emails online to trash..... I need to know the path to the folder so i can delete them all there...please help.
It depends on the email app you run. Probably in /data/...<somplace>.
The problem is that if the phone isn't rooted, if you look in the /data directory you don't see anything - everything in there has read permissions only for the owner and group.
