I have huge music directories that I transfer and synchronise between V20 and PC it is always a little painfull,

How do you synchronise most of the time?

I do it four ways, depending on the situation:

• Put the V20's microSD in my Fujitsu laptop's card reader and use Total Commander for the PC to copy files from my Synology NAS (or other direction) - all while keeping the V20 off, to not mess up SD-card related settings on the V20 because the card being out.

• Over USB-C to USB-A (USB 3.0 speed) cable to that same laptop, Total Commander on the PC

• Over Wifi, directly to my NAS using Total Commander for Android

• Occasionally also over wired ethernet to my NAS using my Novoo USB-C hub also Total Commander for Android
