An application which was greated using GUIDE can save *.mat files with a cusom extension, like *.MyExtension. What I want is, that I doubleclick in the windows explorer such a file, which will: 1. open my application (probably some settings in windows) 2. pass the file path to the application, so that the data can be loaded. Can someone help me on this?

When you say "open my application", would that be a compiled application, or do you mean that MATLAB should be opened and it should run your GUIDE .m, preferably somehow sending in the name of the file that was clicked on?

Hello, I am interested in this same topic @Walter Roberson, but I dont think there was ever an answer from @Sascha Langfermann. Is there any update about how I can "convert" a .mat file into a customized extension .MyExtension, and to also have a different icon in those files that traditionaly have a matlab icon? Is that something we can work out from the App when saving the data?

Basically, like Sascha, I also compiled an application, and all the data created by this application is stored in a .mat file with its own Matlab icon. I would like to have my own externsion and icon for the files saved with this app.

Opening the compiled app when clicking my file would be great as well, but I think that can be configured in Windows, right?

Thanks!!
