It is normal for the saved track to be much smaller.
And as seldom said the active track is for the entire day. the 20100308.gpx is the entire active log for the 8th of March
When I save the track log to SD chip, does it get the name I give it?
No, not in the SD chip. There's a track log by that name that appears to be only stored in memory of etrexIf I look at the SD chip in card reader there's a file 20100308.gpx, which when I open in mapsource it has 3 "files/entries" - ACTIVE LOG154016 - 1 point, ACTIVE LOG154016 001 - 16 pts, ACTIVE LOG154034 - 1322 pts (all have same date) [I was trying to simplify things in original post]. My test at home was done on 3/8/10 & that's all I did that day.
So I did another test today.
test today: turn on etrex vista HCx, after it's gotten sattelites, goto tracks > setup, clear ACTIVE LOG, turn on track logging, get avg'd waypoint, walk around for a bit, save track log, move it a bit, take another avg'd waypoint, walk around a bit with it, save another track log , turn off track logging, clear ACTIVE LOG, turn off gpsr.
bring it inside to computer, turn on, transfer everything, goto setup > interface > connect
I now have 2 track logs w/ 33 & 21 points respectively
If I look at SD chip I now have 2 files in SD chip - 20100308.gpx & 20100309.gpx. Open 20100309.gpx in mapsource & I have following entries listed under tracks tab:
ACTIVE LOG135026 - 612 pts
ACTIVE LOG140115 - 21 pts
ACTIVE LOG140140 - 822 pts
ACTIVE LOG141609 - 5 pts
So it looks to me as tho the two larger entries correspond, roughly, to the 2 saved track logs, where the first shows where I walked down to stream & the other not; and the 2 smaller entries were bits of logging while I was saving, turn off logging etc. Aside from walk to stream, both logs were done in same area so it's not provable that the 2 longer entries are related perfectly or imperfectly to the 2 track logs, or what the 21 pt entry is.
