MATLAB: How to sort files into different folders

sort files

I have a folder with n amount of files. Each file is saved as follows:
1n1 – type 3.csv
2n2 – type 3.csv
77fn.csv
3n3 – type 4.csv
4n4 – type 3.csv
5n5 – type 4.csv
6n6 – type 4.csv
7n7.csv
And so on. The files end with "type 3" or "type 4" or with a random name. I need the script to save all the files that end in "type 3" in a folder named "X" and the files that end with "type 4" to be stored in a folder named "Y". And the files that don't end neither with "type 3" nor "type 4" to be stores in a folder name Z. Any information is helpful. Thank you!
    ALLfiles='\All_Files\';
    X='\X\;
    Y='\Y\';
    Z='\Z\'
folder= ALLfiles;
data3=fullfile(folder,'*.csv');
directory=dir(data3);
for w=1:length(directory)
    name{w}=getfield(directory(w),'name');
    name{w}= strfind(name{w},'type 3');
%insert if statement, if "type 3" exists in name of the file, movefile to X
elseif "type 4" exist in name of the file movefile to Y
else move file to Z
end

Best Answer

Try this...
Get the filenames:
pathname = '\path\to\current\files';
ext = '*.csv'; % extension you care about
d = dir(fullfile(pathname,ext)); % get the relevant directory contents
filenames = {d(:).name}'; % relevant filenames
Create masks for the groups of files you are interested in using regexp:
mask1 = ~cellfun('isempty',regexp(filenames,'type 3'));
mask2 = ~cellfun('isempty',regexp(filenames,'type 4'));
mask3 = ~mask1 & ~mask2;
Copy (or move) the files from their source location to a new destination using copyfile (or movefile):
src = fullfile(pathname,filenames(mask1));
dest = fullfile('X',filenames(mask1));
cellfun(@copyfile,src,dest);
src = fullfile(pathname,filenames(mask2));
dest = fullfile('Y',filenames(mask2));
cellfun(@copyfile,src,dest);
src = fullfile(pathname,filenames(mask3));
dest = fullfile('Z',filenames(mask3));
cellfun(@copyfile,src,dest);
