I have just installed the Android appon my Motorola Moto G 4G LTE.
I assume that while your info shows that the app is written for RootsMagic V3 to 6, in fact it now also supports V7..
I see that you recommend file transfers using Dropbox. However I usually transfer files between W10 and my phone by plugging in a USB cable, changing the permission from charging to file transfer, and drag-and-drop files across.
But I see I have to create a destination folder to do this. Windows Explorer opens the directory MotoG3 > SanDisk SD card and a large number of subdirectories such as Android (with subfolders), also Document and Download and etc., and of course DCIM > photos where I can retrieve the photos of taken, and Pictures where I can transfer photos from my computer.
So I am wondering what directory tree I should create, and place the RMGC file in?
