I guess not enough people complain to the device manufacturers about their MTP drivers.

Impossible!
4 years passed (yes, now 2019) and I suffer same problem on Windows 10 and Note 9!

Wow - so bad and not stable SW!

Kill/restore explorer seems heavyhanded, but it works. I use this trick:

Thank you! You saved my ass, man.

My MediaMonkey always stopped sync at "removing old content" (it hangs for >1 hour without any change), no matter which device I used (Android 4.4.2 on Samsung Galaxy S5 and Samsung Note 10.1 - 2014; Windows 7 x32).

Killing "Explorer.exe" and restarting it solves the problem!

WiFi works quite well and might be nice for casual users, but churning 6000+ songs on my card and weekly syncing, it it waaaay too slow.

If you know something about Explorer in Windows hangs it up all the time, why can't this be fixed?

[quote="terryo"]Why hasn't this hang been fixed?[/quote]Don't know, had the same problem with other programs or just Windows Explorer itself. Not sure if the problem lies with Windows (several versions have this for me) or the device drivers (some devices seem to work better than others). For file transfers I've moved to wifi as well as MM sync works so well over wifi.

My system behaves exactly as described, right down to killing Explorer to speed it up. Why hasn't this hang been fixed? I'm regularly syncing between 4,000 and 6,000 songs and using wireless is too slow.

I am syncing with a Galaxy S4, and MM has been stuck on "removing old content" at the same progress for about 1/2 hour. Is this normal? Seems like it should be done by now.
