[Users] Size of each sub-dirs ?

[Alain Coulais]

Hi

I am a long term user of Claws-mail on Linux,
thanks a lot for this great software !
(before I used xfmail ;)

I was not able to find a way to know the size
of sub-directories (to know the cumulative size
would help to clean up the biggest sub-dirs ;)

I looked for that in the web site, the doc, the FAQ
and also in the archive of mails.

Thanks for the help

Alain C.
