navobj Error Parsing

[Johna1]

Waypts, tracks failed to display.

In the log is "Failed to load C:/ .....navobj.xml: Error parsing".

I suspect this occurred when computer was powered down before OpenCpn was closed.

I would like to recover the tracks.

Any suggestions?

Thanks

In the same folder where the navobj.xml lives, there are back-ups navobj.xml.1, navobj.xml.2 etc.

Rename the active one and get the latest back-up, removing the .1

In case you want to try to repair the old navobj file manually open it with a real text editor like Notepad++, not the standard Windows Notepad.

Thanks

I am aware of the .1, .2 , .3 etc and have rename so I have the previous one.
Thanks for the tip on using a "real" text editor. I am not sure what to look for in the file though.

We of course don't know how much it got broken during the power outage and what exactly got broken - it might be it is is missing one tag at the end, but it also might be completely empty. Look at the good one you have now and on the broken one to see the difference.

Tool like Meld will come handy.

Good luck

Thanks All
The log says exiting cleanly at the time of the accidental pwr off.

I have the navobj with the date and time consistent with the time of the accidental pwr off and the file size is larger than the previous size but the contents of the file is cutoff at a date some time ago. Soo It looks like I am out of luck.

Perhaps I will have a use for Notepad++ at another time. My preliminary plan was to paste the contents of the two files in Excel and do a side by side comparison. I did paste the 1st one in but it was obvious no need to paste the 2nd.

A quick look at Meld url and it appeared to be a Linux application.
Thanks

Weird.

It is hard to cut off the navobj file at a date, especially as it's content is not ordered by date, but by object type. That it is corrupted does definitely not mean that all the data in it is useless/lost. We would have to see it.

Excel is really not a very good tool for this kind of stuff, although it sure can be used if you know what you do.

No, it is a cross platform tool, working on Linux, OS X and Windows (Direct link for Windows download: https://download.gnome.org/binaries/...16.2-win32.msi)

Thanks again Pavel

By some stroke of luck I have made some progress.

I am not sure how but when I click on an xml file it is opened in an xml editor and it points me to an error.

At some point in time I probably downloaded the xml editor when trying to create charts or?

I will attach a PrtScr of this page and a side by side of the Copy & Pasted into Excel of the good file the 10th (of October) and the corrupt file 11th

I have not tried to correct the error - one step at a time.

Might it be worth to tyr run

chkdsk -f

to see if the shutdown made some file corruption that can be repaired

[Johna1]

Good thought but no errors found

Also it seems after correcting the error with Notepad++ the xml editor will display less of the file than before with

The following tags were not closed: gpx, trk, trkseg, trkpt. Error processing resource 'file:///
