From version 2012a on it takes 15+ seconds to change folders in MATLAB. Doesn't matter if I double click a folder in Current Folder panel or use cd in command line.

I have Simulink and Control Systems Toolbox installed. I also have open source toolbox ODTBX installed. I've used versions of ODTBX before 2012a and didn't notice the problem.

I'm using windows 8 and I do use offline folders. I think it may have to do with offline folders because I just noticed when I work offline, changing directories becomes instantaneous.

For me, it's instantaneous. Are you using Windows XP with some mapped share drives? When I had that, there were occasions that it took forever, not just in MATLAB, but any program that tried to change directories or bring up a File open dialog box - had something to do with asking the network drives for something. There was a fix but I don't remember what it was.
