Hi, I made pull request to simple change in code for upload to subdirectories. it maybe isn't best solution, but it works. because on windows you can't use / or \ in filename. so i made little change with regex expression replace that looks for "%2F"(could be only %) in filename and replace it with /. it only changes first argument(name of file), second argument which is full path to file is unchanged. I try it by myself and it worked(it was only try, i dont even hope to work like that). I'm not work in C#, so i must use google to help me with that :D my pull request. i would appreciate if you make some update from that.
