Prolemn with close Matlab folder

Hi everyone,

I have a problemn like the picture. When I use Matlab program, I try to rename the folder containing *.mat files. Although, all files had closed, I can not rename it. Can you help me? Thanks a lot!

Because another program still use this folder or files in folder, so you can not modify it's name.

Maybe, you restart Matlab, it will be OK.

If you do not know which program using , please restart machine.

[galaxy]

Your name same my younger sister name.

Which university do you learning ???

[Walter Roberson]

You cannot typically cannot rename a folder that is your current directory.

Answer 1

[galaxy]

You need to check movefile function which you used is OK or NG

1. Original, after cd command.

2. after use movefile

3. after use rmdir

Because you jump to testpatient folder, so you can use rmdir('Opt_data') only.

If you still problem, if you can, please send me the source code, I want to see it

[thu nguyen]

I sent you the result of each step as three figures below

[thu nguyen]

I sent you the code program.

After you extract the file rar. You have two folders: RunOpt and Patients.

You open the folder RunOpt and run the file run_opt.m.

The folder Opt_data which I need delete is in folder Patients.

I can not attach the files. Can I send you by another way?

[galaxy]

Actualy, I do not know why. I tried on window, Matlab 2015a and 2019b, it was OK.

If you use window, you try my function which I attach to instead of rmdir.

func_rmdir('Opt_data')

[thu nguyen]

I tried your func but it also has error as following.

>> func_rmdir('Opt_data')

??? Undefined function or method 'narginchk' for input arguments of type

'double'.

Error in ==> func_rmdir at 2

narginchk( 1, 1 );

I put your func in the same folder as the folder Opt_data which I want to delete.

I used Matlab 2010b for compatibility with other my code.

I try to send you code but the error as below.

[galaxy]

OK. I understood.

Because your Matlab version does not support it.

Please comment as following and try again.

function    [ st, msg ] = func_rmdir( folderspec )          
    %narginchk( 1, 1 );
    
    dos_cmd = sprintf( 'rmdir /S /Q "%s"', folderspec );
    
    [ st, msg ] = system( dos_cmd );
end

besides, in this website, you can not send to me about .rar file. can you change to .zip file

[thu nguyen]

The func works but the folder is still there.

[thu nguyen]

I sent you the code and the guide to run as following

After you extract the file .zip You have two folders: RunOpt and Patients.

You open the folder RunOpt and run the file run_opt.m.

The folder Opt_data which I need delete is in folder Patients.

Thu san

I ran code as I said before, it was OK.

So, problem is Matlab version old, i think.

You should update your version, minimum is 2015a.

[thu nguyen]

I appreciate all your helps. I will try on Matlab 2015a.

By the way, if you can, you can tell me where you work.

[galaxy]

Currently, I am working in Japan.

When you change to 2015a, only 1 problem will occur. From 2013b, matlab did not support matlabpool function. So you need to comment (line 49 - 51 of start_optimization.m) or change as you want.

=> I commented, and your script ran perfectly.

[thu nguyen]

Now, I see that why you call me "Thu san".

I will try your recommendation. If I have any problem, I will send you question.

Thank you so much!

Answer 2

[thu nguyen]

Thank you for all your answers. When I renamed, I tried many ways such as

1/ Closed all programs

2/ Change current folder

But it did not effect.

Only I restart Matlab, I could rename the folder. But it is not convinient.

By the way, I work at University of Science, Ho Chi Minh city, Vietnam.

Thu Nguyen

[galaxy]

In Matlab, you can modify any folder's name if this folder is contained in Matlab path.

In this case, maybe you rename after you used files or addpath to this folder. So you can not.

You can check Matlab path by

>> path

Besides, nice to meet you. I am Vietnamese too.

It you have any problems about Matlab, you can ask me

[Image Analyst]

Did you have Windows File Explorer open viewing that folder? That might prevent renaming.

Answer 3

[thu nguyen]

Thank to all helps!

Nice to meet you, galaxy. It is so great!

I checked your recommendations, but it did not work.

And I also checked the Windows File Explorer open viewing that folder. I closed all, except the window to rename the folder. But it also did not work.

[galaxy]

I can’t believe that happened.

Please close all application, folder in your machine and tell me procedure you use MATLAB.

ex:

• open MATLAB

• rename of New Folder to xxx
• error occur

Answer 4

[thu nguyen]

These are the paths in Matlab.

[Walter Roberson]

There should be many more items than that on the path.

You should use

restoredefaultpath
rehash toolboxcache

and then use pathtool to add those D: directories to the bottom of the path, and then save the path.

[thu nguyen]

I used

restoredefaultpath

rehash toolboxcache

and the default Matlab come back.

But I don't understand why I add the directories to the bottom of the path because I want to these functions in these directories being the first.

[Walter Roberson]

Whenever you add functions to the top of the path, they take priority over any built-in functions by the same name. That can lead to problems for a variety of programs, not just when you are using that particular software. If you add to the bottom of the path, then any function names that are duplicated would only be a problem running that particular software.

[thu nguyen]

Thank you for your explaination to me. I will notice that.

Answer 5

[thu nguyen]

Thank for your consideration.

The procedure as following,

Step 1:

Open Matlab program

cd (‘D:\Thu_30-8-2015\Phd\Matlab_program\code-checked\code_demo\RunOpt’)

Step 2:

Run the *.m file (run_opt.m)

The result of this step is the data which is in folder Opt_data and some figures.

Step 3:

Change the name of folder Opt_data to other name so that I can restart the procedure.

In this step, the paths of Matlab

And Current folder in Matlab is

D:\Thu_30-8-2015\Phd\Matlab_program\code-checked\code_demo\RunOpt

While, the folder I need to rename in the path is

‘D:\Thu_30-8-2015\Phd\Matlab_program\code-checked\code_demo\Patients\testpatient\Opt_data’

When I tried to rename the folders by closing all windows, except Matlab program because I need it to run again, I can not

.

rename.

So I must close the Matlab, then I rename. After that, I open Matlab and restart the procedure. It is time consuming.

[galaxy]

Thank you for your reply.

Problems in run_opt.m script, please check again.

although you rmpath, but maybe it still contains use *.mat or figures in Opt_data folder.

If you need to run again, you can change name via script, it will fast

[thu nguyen]

I can rename the folder via script by function 'movefile'. The data in the old folder moves to the new folder, but the old folder is still there. The older folder is empty folder now. I want it disappeared.

I will check all again.

Thank you so much.

[galaxy]

After you move files to the new folder, you can use rmdir function for delete old folder

https://www.mathworks.com/help/matlab/ref/rmdir.html

[thu nguyen]

I had used rmdir function to delete the old folder after using movefile function to rename the folder. But it can not delete.

rmdir('Opt_data')

??? Error using ==> rmdir

No directories were removed.

[galaxy]

You need to put full path of folder.

[thu nguyen]

I also checked your recommendation. It also doesn't work.

rmdir('D:\Thu_30-8-2015\Phd\Matlab_program\code-checked\code_demo\Patients\testpatient\Opt_data')

??? Error using ==> rmdir

No directories were removed.

[galaxy]

You received this error because folder not empty.

You need to use rmdir after you use movefile, when Opt_data was empty,

Answer 6

[thu nguyen]

I checked your recommendation, but the result as following

>> cd ('D:\Thu_30-8-2015\Phd\Matlab_program\code-checked\code_demo\Patients\testpatient')

movefile('Opt_data','Opt_data_0')

>> rmdir('D:\Thu_30-8-2015\Phd\Matlab_program\code-checked\code_demo\Patients\testpatient\Opt_data')

??? Error using ==> rmdir

No directories were removed.

[galaxy]

You use movefile wrong.

You move Opt_data folder to in Opt_data_0 folder.

You need move all files in Opt_data folder only.

You can use as below

cd ('D:\Thu_30-8-2015\Phd\Matlab_program\code-checked\code_demo\Patients\testpatient');
movefile('Opt_data\*','Opt_data_0');
rmdir('Opt_data');

[thu nguyen]

I tried your code. The movefile function works, but the rmdir function does not work.

>> cd ('D:\Thu_30-8-2015\Phd\Matlab_program\code-checked\code_demo\Patients\testpatient ');

movefile('Opt_data\*','Opt_data_0 ');

rmdir('D:\Thu_30-8-2015\Phd\Matlab_program\code-checked\code_demo\Patients\testpatient\Opt_data');

??? Error using ==> rmdir

No directories were removed.
