For lazy windows users

You may or may not have your own solution. For those who don't, here is my batch script. When I want to send my app to my device for testing I just drop the file on this batch file. It will open the destination folder and copy the app into it.
Simply create a batch file (*.bat) and paste this code into it. You may need to change the drive.
@echo off
setlocal


rem Set "dest" to the target destination of your file
set dest=E:\GARMIN\APPS


start %dest%
set source=%1
echo.
echo Copying %source% to %dest%
echo.
copy %source% %dest%
