Hello all. I'm trying to reduce my hard drive space used to prepare for a move to an SSD. I've got a wonderful application called DaisyDisk that allows me to visualize data segments on my hard drives. I have three internal drives, and for the time being I'd just like to slim down the size of my startup disk, so I can move it to a smaller SSD. By far the largest segment of my hard drive is a section under Macintosh HD/Users/joelglovier/library/Mail/V2/Mailboxes. This directory is over 75GB. You can see the visualization from DaisyDisk here: http://cl.ly/E7OJ I found this directory before, when trying to slim down my hard drive, and simply deleted it's contents, then changed my settings in Mail.app to not archive attachments, thinking that would resolve the issue. However, some months later this directory has again creeped up to a ginormous size. Can anybody please help me understand what this directory is for, and how to permanently reduce it's size - via Mail.app settings, or whatever I need to change to stop it from becoming so huge. Thank you!
