I'm not following, are you trying to move files to your MSD or off it? I thought you meant into it (as in for long term use on your phone). For short term storage and moving files off, it should be easy enough using your phone's wireless functions or plugging it directly to your computer as you would your thumb drive.
Are you saying that you want to use your phone to record work related content and then move that content directly from your phone to your thumb drive? if so I don't think you can do that, but don't quote me on it (you might be able to on a tablet though). You might just want to bite the bullet and buy a larger MSD card. They are not hard to install, and you can do it in two minutes, even if you have to remove the battery.
