Pretty much exactly what I was describing, however, I have 20 of the GPX files in the Archive, numbered 142-161, meaning the at least some of the first 141 have all gone to binary heaven, and a great deal of tracks (within each archive file) gone. I've captured some of them, some I haven't. I'm quite familiar with the structure of the Nuvi, old and new, because I've had one of some flavor since 2008. The 255W that I had would create a new tracksxxx.GPX file as it filled up the one it had open (roughly 10000 points). Current.gpx had very little info in it other than current position, elevation, time, and heading. With a little diddling, I even got it to report current county with 3rd party maps. The 255W did not record tracks in the Current.gpx file. That was a new thing starting in about 2012, and frankly, I can't really understand WHY there was a need to change the method of saving and archiving the tracks. That's one of the things that actually delayed my 'upgrade' to the 2589 LMT that I now have. But Garmin didn't ask my opinion (nor that of any other semi-advanced user). Other tidbits disappeared in the firmware 'upgrade', too, some of which were cute, some not so much or of much value. My drive designations are K:, M:, and N:. That's strictly a Windows thing, and I've actually had them change a few times when I add a new device. IIRC, the original drive ID's were E, F, and G, because the reassignment hosed up a few scripts I had hard-coded addresses in. Scripts fixed, but still, that's all tangential. Configuring the device as an MTP device makes very little difference in Windows 10, either, except that it's harder to refer to it in scripting.
Garmin protected the nuts and bolts of the GPS OS a little too tightly. There are enough warnings and documents about those warnings as well as an end user license agreement and a dozen other bits and bobs to guarantee that Garmin is not responsible for me bricking my GPS. So why lock it down so tight? One would think that at least SOME of us would realize "I shouldn't have done that!" and can go buy another unit if we brick one. Garmin can only make money if I do. Why not provide decent documentation for those of us that ARE capable of understanding it and changing the performance and purpose of our GPS in ways that do not affect Garmin's intent or copyrights? It isn't like I'm going to find out some kind of top secret information that makes me a Double-Naught Spy. I just want to redirect where the unit keeps it's archives. That is an option in the 60CSX and other units in the GPSMAP line, so I fail to understand why it isn't an option in the Nuvi line.
I guess it's the engineering blood that flows through my body that makes me always want to 'fix' something and make it better. (for me)
