The Ubuntu alternative works, but is far too slow. Realized that I can just as well do the xcopy in two steps, first the incremental xcopy to a Win7 folder "Documents" which contains the relevant subfolders, and then copy this to N7 using the USB-cable to /storage/sdcard0/ (or with AirDruid). Or maybe I will copy "Documents" to the Dropbox folder instead.
Even though I don't feel that I need to xcopy straight to N7 anymore with the USB cable, I decided to accept the challenge. It was not too difficult, except I did not succed to install the USB drivers as anticipated in the guide. Installing the ASUS drivers all three (Android ADB Interface, Android Composite ADB Interface and Android Bootloader Interface) show Code 10 in the device manager. (Same with the drivers from SDK, which seem identical except for different date).
Installing SDK with platform-tools and enabeling USB debugging on the N7 resulted in another instance of the Android Composite ADB Interface in the device manager "working properly". Running "adb devices "gave an empty list of devices and "adb shell" gave device not found.
Any suggestion for a guide for installing the USB drivers?
