[pct-l] GPS waypoints, routes, tracks and POI

[awb51]

I have a GPSMap64st, and like all GPS it has its limitation concerning
waypoints (5000), routes (200) and tracks (200). This is all fine for some
shorter hikes. With 1'000 plus miles it is getting a bit more difficult.

Any good hints how to organize the files in the internal and external memory
so they can be recalled or exchanged during the hike without the need of a
PC?

Advice is very much appreciated
