Matlab 2014a deletes M files in actual directory when exit

2 views (last 30 days)
Hi,
Matlab 2014a deletes M files which are stored in actual directory when Matlab is exit.
Do you know why and how I can fix this?
Thanks in advance.
Best regards, Helmuth

The problem of deleting files occurs now also on MDL files. It seems to occur randomly, probably when the MDL file was created with an older version of Matlab / Simulink?

As part of your finish.m file, two items you could consider are:
  • movefile to copy your files to a back-up directory (and perhaps doing that again in reverse in your startup.m file)
  • savepath to save your entire search path so it is created automatically at startup the next time you launch MATLAB.
This same problem came up in the last two or three weeks, but I don’t know what the fix was (if one was found) or if the details were similar to yours.

There is a bug report now available for this issue.

It doesn't do that for me. What version are you using (official, trial, educational, or student)? What operating system? What is the folder name? If you bring up a window looking at the files (like Windows Explorer), and you see the files there, then when you close MATLAB, do all those files vanish? Do they appear in the recycle bin? Do you have a finish.m file that automatically gets run when MATLAB shuts down that might perhaps delete everything?

Hi,
thanks for your reply.
Your questions:
> What version are you using (official, trial, educational, or student)?
Matlab 2014a Home Use.
> What operating system?
Windows 8.1
> What is the folder name
D:\hbosch\Matlab
> If you bring up a window looking at the files (like Windows Explorer), and you see the files there, then when you close MATLAB, do all those files vanish?
Yes.
> Do they appear in the recycle bin?
No.
> Do you have a finish.m file that automatically gets run when MATLAB shuts down that might perhaps delete everything?
No. I do not have this. A finish.m or similar does not exist.
Best regards, Helmuth

Beside finish.m other functions are evaluated automatically when a Matlab session is finished:
  • CloseRequestFcn of figures, which might be invisible and hidden
  • mexAtExit functions define in Mex files
  • The StopFcn of audioplayer objects (in some Matlab versions, but seemed to caused a crash)

Thanks for your reply. I open Matlab and close it directly after the system is ready. After closing, some files in my working directory are gone.
A finish.m files makes sense now to backup all files in the actual directory to somewhere else.

You should not have to do that. I suggest you call the Mathworks to track down that very unexpected behavior, if you can ever get it to repeat again.

Any updates on this? I am experiencing the exact same issue with Matlab 2014b except I use Windows 7 Professional.
Edit: Nevermind, found the fix:
