OpenCPN LOADING7/unloading problem

hello everybody,
for many years and more than 80.000 miles I have been using OpenCPN to my heart's content.


Recently starting and especially ending the program is taking more and more time. The reason is probably that my navobj.xml has grown to more than 80 MB.


Is there anything I can do else than starting with a new navobj.xml? I do not want to lose my tracks and especially not my big waypoint database.


Any advice is appreciated.

Export your routes, tracks, and waypoints to GPX files. Then delete them from your charts. Any time you need an old route, track, or waypoint you can import it from the GPX file where you saved it. There's no need to clutter your chart with a multitude of unused objects.

+1. We run O on a Pi and I find that about a year's worth of tracks is all it wants to handle (sailing/cruising the full year). Now an annual New Year's Day ritual to export and save tracks. Haven't found the need yet to trim waypoints, etc., it's the high resolution tracks that eat up the memory.

Maybe we need a tool to trim down tracks? I leave high-res on when recording, but a year later most (except for a few tricky harbor entries that should be converted to routes anyway) could easily be trimmed to 15-minute data.

I export my tracks every day. The GPX file in the Tracks folder is named with the date (for example, 2021-12-13.gpx). The only object on my chart are those I'm going to use today.

"Maybe we need a tool to trim down tracks? I"
That selection exists. Suggest referring to manual.
