What is significance of STX file. It is used with Developer Toolkit. What information is stored in this file. If anybody knows pls. update me. Thanks

The STX file “contains general texts used by C/SIDE”, as shortly described in the Application Designer’s Guide PDF-Manual.

You can open and read it with Notepad application, but you can’t edit it.
