File Structure? (on nuvi 560, files I can delete)

 

Where can I get a brief description of the file structure on my 560? I am getting quite a few "memory full" errors, and I'd like to find which files I can delete.

Thanks,
Earl

Not sure if this is what you

Thanks...

Thanks, but what I'm really curious about are just what files store routes, favorites, etc.

I deleted all my favorites and reloaded them. In teh process I lost a few that I had saved from various POI's. The problem MAY be solved now, I'm not sure, since I've only "booted" the GPS once since then.

Hidden partitions

Your GPS has a hidden partition that's not seen when connected to a computer and that's where many of these files reside.

An entire partition is hidden?

How can I "see" that partition? I already have Microsoft Windows set to show me all files, even hidden system files.

I wonder if my "memory is full" errors are related to that HUGE .jcv file that was discussed last week? I downloaded it and put it in my unit.

Hmmm

Hmm, I've read before that nuvi disks contain partitions other than the one seen and manageable as a standard computer drive via Windows--and this made sense to me--but I never looked to confirm this. On my nuvi 855, you finally made me check and see what I could find. Odd, with Windows 7's Admin Tools (Computer Management/Storage/Disk Management) and with EASEUS Partition Master, I looked and from what I can tell now, my nuvi 855 contains just the single partition, the one we can view from our computers. If this is true for all nuvis, then there aren't other partitions--at least not a partition visible by partitioning software. Maybe we need Evert or some other computer guru to shed more light on this topic. It does mean that files containing data not visible on the nuvi drive (maybe tracklogs, favorites, routes, etc.) are being stored in some other inaccessible location but not on another partition.

Getting to your 2nd point, yes indeed, the large 750-ish MB jcv file could be your problem. When you look at your 560's files on your computer, what does your computer's "Computer" say regarding your nuvi's drive? On my 855, my Windows 7 "Computer" says I have 1.0GB free of 3.48GB. But this free space came from my deleting all non-English Help and Voice files and by my putting my jcv file on a SD card rather than locating it to the nuvi's internal drive.

So the big questions for you now are:

-what size drive and how much free space does your computer report on your 560?

-if low on free space, can you delete (after a full backup to a computer drive, of course) unneeded files; e.g., non-English voices, etc?

-I'm not sure about the 560, but many nuvi models can run the jcv file from a SD card and if your 560 is among these, you can transfer the 750MB jcv to a SD and delete it from your 560's drive.

So let us know what free space you see on your drive now. And if there are folks knowledgeable about the 560, does anyone know if the jcv file can reside on a SD card and work with the 560?

LOTSA' room!

Interesting about the partition, or perhaps NOT the partition... smile

With the small .jcv (about 446 Mb) installed in the internal memory, the 560 shows I have 3.61 Gb free, out of a total of 7.31 Gb. I've not deleted any voice or text files, I guess I probably don't need to.

I've been running the .jcv on an SD card for several days, and it works fine. It's just this "memory is full" blurb that pops up when I first turn the GPS on. It happens with either the 446 Mb or the 752 Mb file. Actually, everything seems to run OK, it's just annoying.

The next question I have is just WHAT memory is full???

BTW...

With the large .jcv file installed, it shows 3.31 Gb free. Sounds about right.

I wonder about a hard reset

I wonder if a hard reset of your device may end the phantom error.

Even odder - back to partitions

OK, maybe there are hidden partitions and my Windows software can't find them on various devices.

I have a nook color ereader which is a 8GB device. I know from reading that the device has two partitions, one visible and one hidden. In using the Windows 7 and EASEUS partitioning software to see what the nook color shows internally, I see only the 5GB visible partition and I don't see the 3GB hidden one.

So I now return to my first thought which is that Garmin devices have hidden partitions that contain files like maybe tracklogs, favorites, routes, etc. and that not only am I unable to see these files, but I can't even detect the existence (or size) of these hidden partitions.

So back to the OP--maybe a hard reset will clear some files on these unreachable partitions and clear your phantom error. If what I'm thinking now is correct, it's also impossible when the GPS is USBed to a computer to look for and see the files in hidden partitions, at least when connected to a Windows PC.

Just got back from Denver...

Sounds about right -- need to delete files, but can't delete them with the computer.

Lessee -- how do I do a hard reset?

Maybe someone with a dezl 560 can confirm that this procedure will work for you. I don't think I've read about anyone with this new trucker model having tried.

Oh wait, paste this link into your browser for the direct-from-Garmin answer:

OK...

I'm gonna give this a try...

Odd...

How strange -- it asked if I wanted to delete all user data, and when I answered "yes", it deleted trip logs, all the IFTA data I had input, i.e. fuel prices, locations, etc., but left all my favorites and custom POI's. I'll try it for a while and see if the memory problem is gone.

Memory full

All you need to do is connect your garmin to your computer and find the archive file and open it then open the file called GTX then highlight everything in this folder an delete it. I have to do this about once every couple of months. The GTX file is garmins temporary folder where it stores calculations and recalculations, when it gets full you'll get that memory full unable to calculate route error message.
