T0biasCZe: Android MTP is extremely slow... so I made my own application with C# and ADB thats 28x times faster. Perhaps you may also find it useful... :D
I was getting tired of the mtp throwing errors half the time, the directories loading two minutes (not exagerating), the copying taking taking hour, so i said screw it and made my own file transferer that uses ADB, which doesnt rely on the slow as MTP. I made it primarily for myself, but since i already made it why not share it...
