Just what the doctor ordered, but:
1) The ability to organize individual files into folders would be nice.
2) Fairly intuitive, but some might not know what to do with the IP & port no. that appears after Start when transferring files since the caption is in Chinese.
The app is fast & fairly intuitive at transferring files from PC to iPhone, via wifi anyway. (Havent tried the other methods.)
