Information about the .opt (opt) file type

Below is all the information we have available on file about the .opt (opt) file type.

.opt
Microsoft Visual Studio file. Holds working workspace configuration information, such as current window and breakpoint positions. This file can be safely deleted and will be recreated on demand, but with the resultant loss of some information, such as breakpoint positions etc.

Where this is available we would like to include file format information on .opt files, as well as information on how to view or open files of type .opt. If you know of any information which we have missed then please let us know.
