Rename all image files (e.g. jpg) in a folder according to the file modification date

Dear all,

I have been looking for a solution which helps me renaming all the JPG files I have on a folder according to their file modification date. However, any of the solutions I came with worked out for me... At the end, I would like that all the files in my folder have the following format: 20200212_1000, for instance...

Thank you very much in advance for your help.

Kind regards,

Joseba

Get the all jpg files

d = dir([path, '\*.jpg']);

Apply loop for each image file of the directory and get the filename

filename = fullfile(d(loop_var).folder,d(loop_var).name);

Get the image modified date and rename using reguler expression

filedetails = imfinfo(filename);
file_time_stamp = regexprep(filedetails.FileModDate, {'[-:]',' '}, {'', '_'});
renamed_filename = [file_time_stamp, '.jpg'];
renamed_filename = fullfile(d(loop_var).folder, renamed_filename);

Then move(rename) the file with modified name as

movefile(filename, renamed_filename);
