@armin m, I believe you're mistaken when you say "properties>read only? It acctually change your code. If you change your code and accidentaly click on overwrite button which appear in run mode when you change read only file code."
I did exactly that. Made a file read only via the properties in file Explorer. That (changing property to readonly) did not change the code because when I opened it up in MATLAB's editor it was the same. However, I made a change to it and tried to save it and it said:
There is an "overwrite" button like you said and if you click it, it will save your changes and uncheck the readonly property, like you told it to. It gave you a warning but if you said to ignore the warning and do what you told it to do (overwrite), evidently it will trust you know what you're doing and do what you told it to do. Like it or not, that seems to be the way it operates.
So (1) don't change it, and (2) if you did change it, don't overwrite it. And (3) if you did overwrite it, get the original copy from your archive or backup.
