How to select files in a directory
28 次查看(过去 30 天)

Hello,
I created a directory which contains a lot of DICOM files (IM_0001, IM_0004, ..., IM_0025, IM_0028, IM_0031, ..., IM_0052, ..., IM_0088) using :
listing = dir('IM*.*');
I would like to select only files which names are between IM_0025 and IM_0052 (IM_0025, IM_0028, IM_0031, ..., IM_0052) and save them in another directory.
Is there any function that may help me ?
Thank you in advance !

listing = dir('IM*.*');
for K = 1 : length(listing)
fname = listing(K).name;
if ~strcmp(fname(1:3), 'IM_'); continue; end
fnum = str2double(fname(4:7));
if isnan(fnum) || fnum < 25 || fnum > 52; continue; end
copyfile(fname, 'NewDirectoryNameGoesHere');
end
or use movefile() instead of copyfile() if you want them moved instead of duplicated.

d=struct2cell(dir('IM*.*'));
name=d(1,:)
for k=1:numel(name)
file=name{k}
v=str2num(file(6:end))
If v>=25 & v<=52
copyfile(file,'yourfolder')
end

% run once for, see if the 'move file' output is ok
% if ok, uncomment the movefile line such that the files are actually moved
listing = dir('IM*.*');
dstdir = './newdir'; % where the selected files should be moved
for i = 1:numel(listing)
filename = d(i).name;
[num elements_matched] = sscanf(filename, 'IM_%d');
if elements_matched && num >= 25 && num <= 52
disp(['move file ' filename ' to ' dstdir '.'])
% movefile(filename, dstdir)
end
end
