Can PM's be stored in a folder and removed from inbox?

Your overall PM capacity is at 90%, meaning all PMs in the sent folder and inbox are taking up that much space.

You can move important PMs off to other folders by creating a new folder and moving the PMs over. Click here to do so.
 
Thanks, Vlad! This helps tremendously! I don't know why I never figured this out before. :P

Is there a way to move messages in my Sent Items box to folders? It doesn't look like this is possible.
 
that's what I thought but I only saw the option to delete, mark as read/unread and download. I did see the option to move to another folder but I thought it meant one of those I listed above. I did try that one though and it worked. Thanks!
