Can you open it if you change the extension from .MDL (all caps) to .mdl (all lower-case)?


Thanks for your response
As the file cannot be opened, i can not chage its extension.
If you know a way that allowa me to change the extension of the file, kindly write it down please
You can use the movefile function in MATLAB to rename the file, including its extension. Though if you're on Windows, you might want to copyfile it to a file with the correct case for the extension in tempdir first, since Windows and filenames that differ only by case don't play well together, if I remember correctly.
