Geocaching Australia

I am running a Garmin Oregon 300 and with the geognome race changing so much, I got the great idea of not pushing my pocket query through GSAK, and instead just copied it straight to >garmin\gpx\*.gpx.
Now I noticed they all pop up in my 'waypoint manager' and now I have no more room to save any of my own waypoints.
So I removed the gpx file, only to find all the waypoints still on my GPSR.
I want to get rid of all of the moving caches out of my GPSR, and re-acess how to properly manage the file.
However, I don't want to just use the 'bulk delete' function as I also have a mutitude of saved, solved, and future waypoints and caches stored as well as the work related waypoints.
Is there a way I can quickly delete a multitude of waypoints from my device? I was doing it one by one manually for about half an hour, but I have not made much progress.
please help a stupid person.

I do not have the mapsource program.
thankyou

Hi. The Mapsource and/or Basecamp programs for Garmins will make life a whole lot easier in this regard. They both do pretty much the same job of organising your user data, but go about it slightly differently.

no real keyboard here. forgive brevity

load waypoints into blank gsak db
clear all with
ON GPS

SETTINGS
RESET
DELETE ALL WAYPOINTS

tidy gsak
send to gps

Did this work? It looks like a very elegant solution to me!
