I suddenly cannot save m-files anymore. What can I do about that?

When I create a new m-file and want to "save it as..." it does not change its name from "untitled" in the Editor and the little star telling i is unsaved does not disapear. Then again when I open and change an existing m-file I can save it as usual. I am using version 8.0.0.783 (R2012b).
Tanks for your help!!!

Please run PSR.exe (Start>Search Programs and Files->psr, or whatever the equivalent way to find programs in in Windows 8) and record your session and upload to your favorite file sharing web site. Then tell us where you uploaded it. http://www.mathworks.com/matlabcentral/answers/7924-where-can-i-upload-images-and-files-for-use-on-matlab-answers That way we'll see exactly what you see in a series of screenshots.

copy your file content to text file(notepad for example), restart matlab, and save your file

NTFS permits 2^31-1 files per subdirectory. If you are exceeding that, you should be reorganizing.
FAT32 permits 65534 files per subdirectory. That might apply for something like a USB stick.

I'm saving the files on my laptop computer and I don't even have that many files in the folder, less than 20 files. 10 images and 5 code snippets max.

What operating system are you using and where are you trying to save it? Windows 7 does not let you save in certain folders even though the save file dialog will let you browse there.
Does the dialog box just exit as if everything went perfectly normally, or does it give you any kind of error message? If there is no error message, it should have worked and changed the title bar name in the editor. If it doesn't behave that way, I'd call the Mathworks.

@Azzi: After dozens of years of experiences with computer users, I've learned that "suddenly" means: directly after a modification I do not tell here, because I either do not assume that it is important or I'm even not aware of it.

Got the problem description right, but still no solution. It seems totally bizarre and unexplainable so you need to call tech support.

We have a few reports of this happening (including from me!) so please contact us so we can learn more about it.
One user resolved it by reintalling Windows.

This just happened to me! There was no error message and I could go through the save process as per normal, but the script is not saved (remains as untitled).
MATLAB R2021b, MacOS Mojave, v10.14.6
(update) Actually, I cannot run any scripts at all

@Jing Ci Neo, call tech support. Not being able to run any scripts at all is not normal. Tech support can start a screen sharing session with you and fix it. We can't do that.

I have the same problem.
I believe that the problem has been in the updating of jdk from 1.6 to 1.7 and the declaration of the environment variable MATLAB_JAVA...
check it anyway...

Hi,
Today I had exactly the same problem.
Matlab release: 2019b
OS Windows.
Now it seems to work fine but just to keep issue stats updated.
Best.

Did you see my comment at the top about running PSR?
Attach the zip file it creates here with the paper clip icon so we can look at it.
