I would like to see you add a fourth text box to store the default folder to convert. I know I can click "convert folder" and the last one I used is selected in that dialog then I can just click, but it would be nice to just stat the app, click start and it goes using my default settings. My folder locations are not going to change and if they did, I am competent enough to adjust them accordingly.
To your last point, I can tell you from experience that it will not matter how many signs, flags, flashing banners, jumping sprites, big giant arrows, etc you put on there, you will have some people miss it. I deal with it almost daily, you should see some of the things I put on my screens. Short of having them send you the files and you doing it for them, you might try rewording the labels to be more clear. Terms that seem second nature to developers or designers don't always come across like we intend to the end user. Plus, no one reads docs anymore and watching videos seems to take too time.
So maybe something like:
*Where are your ORIGINAL Bovada files downloaded? - browse to folder - tooltip stating these are the ORIGINAL files downloaded form the Bv client. (assuming you take my suggestion above
)
*Where do you want the ORIGINAL UNCONVERTED Bovada files moved after processing? - browse to folder - tooltip stating these are still the ORIGNAL UNCONVERTED files and are moved for archival and performance reasons.
*Where to you want the CONVERTED files stored? - browse to folder - tooltip stating these are the CONVERTED files and the one that PT and HEM should use.
Very wordy and doesn't make for a pretty screen, but if it clears it up for your users, probably worth it.

Edit: I see you store the history folder in the config file, so it should be easy to add a "Convert folder using default settings" button or something
