Renaming of image filenames inside the folder

Hi,

I have 9721 .bmp images stored inside the folder with file names starting from C001H001S0001000001 to C001H001S0001009721, I need to rename all the images to D00001 - D09721. May I know how to do this?

Hi,

Assuming that all of the '.bmp' files are stored in the same folder, the renaming can be done using a MATLAB script using a 'for' loop to iterate over all the images. This can be done as follows:

directory = 'path/to/your/images'; % Replace this with the path to your images

% Get a list of all files in the folder
files = dir(fullfile(directory, '*.bmp'));

for idx = 1:length(files)
    oldName = files(idx).name;
    
    % Extract the numeric part of the original filename
    numStr = oldName(14:19);
    num = str2double(numStr);
    
    % Generate the new filename
    newName = sprintf('D%05d.bmp', num);
    
    % Full path for old and new names
    oldFullPath = fullfile(directory, oldName);
    newFullPath = fullfile(directory, newName);
    
    % Rename the file
    movefile(oldFullPath, newFullPath);
end

Hope this helps!

Thanks!

I think the below part of code needs to be modified. It would be better to replace the entire old file name by new name rather than extracting the numeric part of the original name.

  numStr = oldName(14:19);
  num = str2double(numStr);

I have modified another code from different forum, which works fine.

Thanks!
