You can load your excel file using the readtable funtion.
myexcel = readtable('myexcel.xlsx');
You can the use the dir function to list all the dir files in the directory and its subdirectory.
mydir = 'C:\somedir\';
myartfiles = dir(fullfile(mydir,'**','*.art'));
You can then compare the filename and then copy them using the copy file function.
mycopydir = 'C:\copydir\';
samefiles = ismember({myartfiles.name},myexcel.name);
filestocopy = myartfiles(samefiles);
for i = 1:length(filestocopy)
origpath = fullfile(filestocopy(i).folder,filestocopy(i).name);
destpath = fullfile(mycopydir,filestocopy(i).name);
copyfile(origpath,destpath);
end
