my quick research on LQ and with my favourite internet search engines hasn't given useful results, but if I am missing something, please just give me a pointer into the right direction. During the migration to Slackware 13 and KDE 4.2.4 I observed something I don't understand regarding KMail.
My understanding is, that KMail stores email messages by default in ~/.kde/share/apps/kmail. Problem is that storage space is calculated differently depending on the PWD and command I use.
Using du in kmail I get:
user@linux:~/.kde/share/apps/kmail$ du -s -m *
Now, when I change into mail in order to check the size of the sub-folders and files there, I get only small numbers, that never result in the 2102 MB computed by su:
user@linux:~/.kde/share/apps/kmail$ cd mail
user@linux:~/.kde/share/apps/kmail/mail$ du -s -m *
I'd be grateful, if anyone could give me a short explanation, what's going on here, and if this behaviour is correct or indicating that something's fundamentally wrong with my system.
If the figures of both commands are correct: Where are the missing 1800 MB, then, not seen by the second du?
Thanks in advance!
