Hello, I want to know what is the command for closing a particular type of file without any requist to save it.
i.e. I want to know:
  • How can I close all files from any type of application e.g. close all txt files that are open?
  • How can I close those files automatically without saving?
I already know, for closing an excel file the following commands are used:
However when I use code, the application, (in this case excel) asks me if I want to save my file.
Excel = actxGetRunningServer('Excel.Application');
Excel.Quit; % Shut down Excel.

Is "fclose all" what you want?

Excel = actxGetRunningServer('Excel.Application') will run the external exel server. You can check to see how the external server Quit the file without confirmation.
Try the follwing to see if you can skip the confirmation.
Excel = actxGetRunningServer('Excel.Application');
Excel.DisplayAlerts = false;
On the other hand, if you can replace the actx and use xlswrite, then you will not have the problem of confirming quit.
