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?
