How can I sort files into different folders?

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

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);

Hmm, can you tell me what pathname and filenames(mask1) look like for you? Pathname should be a string and filenames(mask1) should be a cell array of strings.

Thank you! this worked. Just needed to add a loop to run through all files
