TZT13X Importing tracks

[jimb]

I have a new TZT13X, replacing a NN3D. I exported the old tracks from the NN3D as CSV, and put them on a USB drive as the file ACTVETR_trk.csv. So, it's one long 10,000 point file covering several years. I imported this to the TZT13X and it imported and shows on the screen correctly, albeit as one long track. It did not break it up into individual tracks by date, although date information is in the file. So, pretty good so far. However, it's not saving it as a track. When I shut down the TZT, and restart it without the USB drive, the imported track is gone. Re-importing the tracks puts them back, but just until the TZT shuts down again. I also don't see a command to properly eject the USB drive. It seems like I'm close but missing something here. I tried renaming the file as something other than ACTIVETR_trk, but it wasn't accepted. Any suggestions would be most welcome!
Thanks,
Jim

Ahh. I figured it out. I split the 10K old track points into each individual day's track. Named each one like this: "Old Track 1_trk.csv", etc. Adding "_trk" made the difference. Now they all imported one by one fine and are listed by date. I can change the color & decide which old tracks to show. Haven't figured out how to "un-show" a specific track, other than by deleting it. Of course it's easy to re-import it now. These tracks stay available even when the plotter is turned on & off. Still haven't found an on-screen button/command to eject the USB drive, but it doesn't seem to bother anything.
Fyi,
Jim
