Do I understand that you want to examine the file modification date of each file, and split the files into different folders by year of modification?

@Walter Roberson yes correct,

Even though same file must be its date modified can stay into same folder and overwrite with older file.

inputdir = 'appropriate directory name';
outputbasedir = 'parent folder for split directories';

dinfo = dir(inputdir);
dinfo([dinfo.isdir]) = [];  %ignore subfolders and . and .. entries

for K = 1 : length(dinfo)
    dv = datevec(dinfo(K).datenum);
    yearstr = num2str(dv(1));
    outfolder = fullfile(outputbasedir, yearstr);
    if ~exist(outfolder, 'dir'); makedir(outfolder); end
    sourcefile = fullfile(dinfo(K).folder, dinfo(K).name);
    copyfile(sourcefile, outfolder);
end

If you want to move the files instead of copying them then change copyfile() to movefile()

If you want to process all immediate subdirectories of a parent directory then use

inputdir = 'appropriate directory name/*/*';
