I can't copy the files, received unknown error

I am trying to copy files to a new folder but I have received unknown error. I used similar code before and copyfile command worked well but this time it doesn't. I couldn't figure it out. Could you please help? Thanks in advance

Please post the complete error message. You do have this important information. Then it is useful to share it with the readers.

There is no fopen() in your code. Why do you close all files brutally by fclose all?

While reading the forums I saw such a suggestion to use fclose all, so tried it. Thanks, I should be careful.

      % Mean Velocity
        filename = sprintf('M1_Normal_T%d_%s_M_Vel.dat',j,word);
        allFileInfo = fullfile(start_path,filename); 

filename refers to a file that lives under start_path but the filename variable does not include that path information.

       copyfile (filename ,fold2);

but there it is being referred to as if it is in the current directory.

I got your point. I should say matlab: this filename in this path, go there, copy it to fold2? Am I right?

How can I include that path information to the file name variable?

Many thanks

You have

        filename = sprintf('M1_Normal_T%d_%s_M_Vel.dat',j,word);
        allFileInfo = fullfile(start_path,filename); 

so allFileInfo is already the qualified version of the file name. copyfile(allFileInfo, fold2)

It works. Many thanks for the help.
