[Dovecot] ot: moving files/dirs from terminal ?

[voytek at sbt.net.au]

warning, dumb question ahead:

I want to re-arrange, rename & create some sub directories below INBOX in
my own mailbox;

if I use 'mc' from terminal to do so, can that cause me grief...?

do I need to ?? re-index explicitly?? afterwards ? how to re-index ?

or is that a really _B_ad idea, and, I should do it through say
squirrelmail client ?

thanks for any pointers!
