I wrote an Edge "workbench" type of program for Microsoft Windows 10.
- Convenient access to the files on your Edge for viewing/deleting.
- Makes it easy to download routes/trips (public and private) from RWGPS.
- Easy to download public courses from Garmin ConnectC (Garmin makes it hard to do anything more).
- Download multiple routes at once by dragging a list of URLs (from an email, for example).
More detail here:
It's available through the Microsoft Store. There's a 30 day trial (it's $2 to buy).
