I would please like to know what to do when I am trying to open an m-file and it displays the following message:

Moreover when I then try to open the file directly in the folder it displays this messages

Error using cd

What kind of device is F: drive and what kind of file system is it and how old is it?

Directory names beginning with ... are not valid in 8.3 naming systems and historically long filename support did not always work properly for CD or early generation USB stick drives.

Please tell us exactly what you did in the first case and the second case.

In the first case, did you see the file in the current folder panel?

In the second case did you use Windows "File Explorer"? Or MATLAB's edit function on the command line? Or something else?

The f drive is disk space on my 64 bit windows 10 operating laptop, i have a partitioned harddrive.

In the first case I clicked the open option on the home tab proceeded to browse through the files so I could locate the m file and when I clicked to open the file it produced this image

In the second case you are correct I did use the windows file explorer to directly go to the location of the file to click to open it but when I did it again gave me an error this time saying

There is a possibility that it would work if you renamed the directories so that there is no space in the name.

However I suspect that instead you might have permission problems. Experiment with starting matlab with Run As Administrator. If you are able to access the directory with that, then you have a permission problem and need to use File Explorer to examine the security settings on the directories to check ownership and permissions.
