JTC file format

[conehead]

I have a bunch of files files from a french data system. Data is binary with a .jtc extension. Anyone have any idea where I can get a program to unpack these files?
Thanks

Have you tried opening the file in Notepad?
If the file came from a UNIX system, file extensions are not a necessity on a UNIX system. One can basically make up your own file extensions on UNIX. So just trying to find out what a file is based on its file extensions is not a sure way to do this.

Try using notepad. You could try using using the dos command "edit" which works as well.
You could also try using a hex editor.
Now if you have access to a unix system, a GNU/Linux system or similar, you can use the command "file" to find out the metadata tagged into the file.

For example. I wanted to find out what filetype the MS WIndows binary "io.sys" is.

The command is "file io.sys"
results are : io.sys: MS-DOS executable (EXE)
