MATLAB: Renames a lot of files in directory

forloopmovefilerename

Hello, I have a lot of .mat files in a folder and I want to rename it from ex : 65300106179 into something like Flight 10001 and so on. Below is my code

f = dir( fullfile( projectdir, '**', '*.mat') );
for kk = 1:numel(f)
  fileFrom = f(kk).name;
  fileTo = ['Flight',erase(f(kk).name,'1000%d.mat'),'.mat'];
  movefile(fileFrom,fileTo);
end

The problem I have is the file name changed into Flight65300106179.mat. Any idea where I did wrong?

f = dir( fullfile( projectdir, '**', '*.mat') );
for kk = 1:numel(f)
  fileFrom = f(kk).name;
  fileTo = ['Flight','1000%d.mat','.mat'];
  movefile(fileFrom,fileTo);
end

Another possible solution:

f = dir('*.csv');
for kk = 1:numel(f)
  fileFrom = f(kk).name;
  fileTo = ['data',erase(f(kk).name,'0.csv'),'.csv'];
  movefile(fileFrom,fileTo);
end

MATLAB: Renaming Files After Unzip

files = fullfile(matlabroot, '\toolbox');

So files is a character vector at that point.

files = dir(projectdir);

Eventually you assign the result of dir() over top of the character vector. But before that, it is a character vector.

[~, f] = fileparts(files(id).name);

And that line is before you assign the result of dir() to files

unzip(fullfile(dinfo(K).folder,dinfo(K).name),selpath);

That tells unzip to write the files into the directory indicated by selpath, which is not likely to be the current directory.

[~, f] = fileparts(files(id).name);

If you were to replace files with a variable that you had assigned the results of a dir() call into, then that line in itself would potentially be valid. It is completely valid to use fileparts() on a character vector that refers to a file that is not in the current directory.

movefile(files(id).name, rf);

If you were to replace files with a variable etc., etc., then the line would still need work.That line requires that the given file is located in the current directory, which will not be the case -- the file is over in selpath
