To pass data from mobile phone to PC, as fast and easy is the Kies program, that if you have to have installed the driver of your mobile on your PC, but does not work, you connect the cable that you came with the phone to the PC and the program in a second, you get caught the phone and longer with the activated, so you do everything you need. If the program does not open on the pc, it is wrong installed.
Your phone does not have OTG think, then no matter how much you insist, you can never do so. You can do it with a file browser (as you said you mate) or up what you need from a cloud (dropbox, one drive, google drive, and so on ...)
P.D .: This sounds to me have already tried. If you is not worth this help, you'll have to wait for the "specialist" who certainly know a better way to do it ...
