Here is some code to get you started:
CopyFolder = './MyFolder' ;
fid = fopen('files2copy.txt');
Files = textscan(fid, '%s');
fclose(fid);
CurrentFolder = pwd ;
cd (CopyFolder)
for k=1:numel(Files)
success = copyfile(Files{k}) % copy to current folder
if ~success,
disp([Error in copying file: ' Files{k})]) ;
break
end
end
cd (CurrentFolder) % back to original folder

Sandy, you're not accepting the success return arguments. It's more robust to do that, like Jos's code showed. Anyway, does it work? If it does, mark the Answer as "Accepted".

fid = fopen('filestocopy.txt');
cell_data = textscan(fid, '%s');
fclose(fid);
mat = [cell_data{:}];
path_03 = 'C:\Users\test\Desktop\sample\';
listing = dir(fullfile(path_03, '*.tim'));
mkdir('C:\Users\test\Desktop\sample\','Filtered Files');
a={listing.name};
a=a';
out=strrep(a,'.txt','');
cc=ismember(out,mat);
dd=find(cc);
for k=1:numel(out)
x=out(dd,:);
end
copyfile(x,'C:\Users\test\Desktop\sample\Filtered Files\');
showing error as

copyfile(x,'C:\Users\test\Desktop\sample\Filtered
