Hi. I want to transfer files on Android (v2.2.2 and v4.3) to "c:\download" on PC (XP and Win 7) when I
connect using USB cable (driven by B4A program only).
You can use SMB library to copy files over the network. However it will require some configuration. The only other option is to create a PC app that will read the file (which itself is not simple as the MTP protocol is poorly supported on the desktop).
