Add support for gpz (zipped gpx) files.

• Smaller total file size saves storage space.
• Associate gpz files with your favorite GPS app.
• Transfer 100% faithfull gpx TBT gpx navigation tracks.

• By the gpx sym will autodisplay the associated transfered icon png images
• By a manual trigger can show map thumbnails of the transfered photos.

Thanks for the nice explanation. It's always good to learn more about something that interests us all 👍

FYI - Dan Foster (Topografix / GPX standard) is strongly in favor of a GPZ/GPX proposal that exactly mirrors the KMZ/KML behavior.

I also believe a GPZ container format (mimicking KMZ) has many pracitcal applications, so I have adapted Google's description of KMZ and tweaked it to describe GPZ. The GPZ description mimicks KMZ exactly, just referring to GPX and using GPZ examples. You can find my description of GPZ at https://logiqx.github.io/gpx-ideas/usage/gpz/.

A discussion about icons and the GPZ container format can be found in the GPX developer forum at https://groups.io/g/gpx/message/222. You'll need to sign up to groups.io to access the icon and GPZ discussion but if you think it's a worthwhile idea, feel free to add your thoughts to the existing message in the GPX developer forum.

Dan mentioned in another thread that he would be busy over the holiday period, but I suspect he'll be able to respond to the GPZ discussion in the near future.

Regards, Mike

What is a schedule for this good idea?
It is over 2 years old but still needed 🙂

@mariush444

Import gpz (zipped gpx) files has been available since Cruiser 4 and now we are in Cruiser 5. 🙂

The announcement is above as answer to this thread:

• GPZ (zipped GPX) files support #127 (comment)

[devemux86]

The original thread idea is for import gpz (zipped gpx) files.
This was implemented a few years ago.

Please avoid constantly editing thread descriptions, as this confuses users.
For feature requests, it is best to create new threads.

We can then discuss the proposal and depending on how many users want it, we can consider it.

I'm sorry, this is my mistake.
You absolutely right
