Editing a Lowrance HDS .USR file

I'm wanting to open a file for editing. They are waypoint and route files for Lowrance HDS units and I am not sure what they are written in. What I would like to do is open them in a text editor type program so that I can search and replace text pointing to the icons to use to multiple points at once and add remove multiple points at once.

The only clue I have is one site that refered to the files as being in "vector" format.

Can anyone help to identify what it is written in or how I can open it and save it in an ediing program?

Thanks,

EE offers us the ability to attach a file.  It is much less annoying than Rapid Share.  Going forward, you might want to use the EE tools.  I looked at the file, and I can't really add much to the AUSFish link.  Files named .usr are often binary data bases of some sort.

The file is captioned "Navico export data file"

More on Navico here:

It looks like there may be some version dependent characteristics to these files.  You might want to contact Navico / Lowrance directly to see what they can tell you about how to process the file -- it might be faster than trying to research it yourself.

Good luck with your project, ~Ray
