When I save a .m file in a folder, MATLAB autosaves a .asv file in the same folder.
I opened this file and I found that it contains my code from the beginning, ignoring what I have deleted.
- What is the use of this file?
- What's the risk if I delete that file?
A .asv file is just what you said, an "AutoSave" file. It's just there so that you don't lose all your code if your computer crashes/shutdown. You can delete it whenever you want.
If you find them annoying you can go to File/Preferences/-->"Editor/Debugger" --> Autosave and turn it off.
