Dear all

i have many folders that exist in certain directory.. every folder includes some images with ambiguous name.. i would like to rename these images based on their its parent folder name.. but the problem in the following code .. images names are numbers like (1245451116 , 4654646654, 44465464 ....) and this code do not able to renaming its :

result perhaps look like the following : folder1 images names becomes : folder1-1; folder1-2; .... folder2 images names becomes: folder2-1; folder2-2; etc...

projectdir = 'D:\RESULT\Evaluation\categorized';
dinfo = dir(projectdir);
dinfo(~[dinfo.isdir]) = [];   %remove non-folders
dinfo(ismember({dinfo.name}, {'.', '..'})) = [];   %remove . and .. directories
num_subdir = length(dinfo);
for S = 1 : num_subdir
  this_subdir = dinfo(S).name;
    subdinfo = dir( fullfile(projectdir, this_subdir, '*.jpg') );
    num_subfile = length(subdinfo);
    for F = 1 : num_subfile
      this_file = subdinfo(F).name;
      old_file = fullfile( projectdir, this_subdir, this_file );
      new_file = fullfile( projectdir, this_subdir, [this_subdir '-' this_file] );
      try
        movefile(old_file, new_file);
      catch ME
        fprintf('Failed to rename "%s" to "%s"\n', old_file, new_file );
      end
    end
end

在 MATLAB Online 中打开

...
for F=1:length(subdinfo)                          % no need for temporary variable here
  [~,n,e]=fileparts(subdinfo(F).name);            % get the name, extension
  fname=sprintf('%s-%04d%s%s',this_subdir,n,F,e); % build new name from the pieces-parts
  try
    movefile(fullfile(projectdir,this_subdir,this_file),fullfile(projectdir,fname);
