This is the process for an Edge, but it is very similar for the watches, just some of the folders are named a little differently.
On the Edge go down in to the Garmin folder and select all the folders and copy them to your PC. Don’t copy the files in the Garmin folder or the Garmin\Maps otherwise you will be there all-day copying maps.
On you PC you have the following folders
Follow the guide below to decide which files you need and where to place them on the new unit or the original unit after a reset.
NOTE. If you have been forced to clear non-vol you may still be able to restore your settings and profiles as the Edge creates a backup of these when it does a software update. These will be as recent as the last update. They are located in the Garmin\Debugging\Backup folder
