Read dataset file name only

Hello, i want to ask how i want my code can read dataset folder name only like the folder name like 0,1,2,3,4,5

the dataset i choose is from = https://www.kaggle.com/ayuraj/asl-dataset

Right now i can only read image name only. So, i want the system can read and call dataset folder name.

Here my code

SelectFile.m

%N = 'C:\Users\USER\Documents\MATLAB\Project\asl_dataset\asl_dataset';
function d = SelectFile(A,N)
M = 6; % number of class [0 to 5 ]
cnt(1:M)=0; % counter for each class

% get all filenames in the data directory
  D = dir(A);
% extract only N file
  d =D(1:N);

% see the statistic of each class pattern  
 for i=1:N
  fn = D(i).asl_dataset; %file name
  x = fn(38);   % extract target from filename
  
  %find the distribution of file being extracted per class
  if (x == '0')
      cnt(1)=cnt(1)+1;
  elseif (x=='1')
      cnt(2)=cnt(2)+1;
  elseif (x=='2')
      cnt(3)=cnt(3)+1;
  elseif (x=='3')
      cnt(4)=cnt(4)+1;
  elseif (x=='4')
      cnt(5)=cnt(5)+1;
  elseif (x=='5')
      cnt(6)=cnt(6)+1;
  end    
 end
 cnt
 bar([0 1 2 3 4 5],cnt);
 title('statistic number of pattern per class');
 text(0:5,cnt,num2str(cnt'),'vert','bottom','horiz','center'); 
end

sample.m

D = 'C:\Users\USER\Documents\MATLAB\Project\asl_dataset\asl_dataset';
d1 = SelectFile(D,360);   
[Dat,Trgt] = FExtraction(d1);
net = NNTrain(Dat,Trgt);

%Test NN using Test Patterns
%D = 'C:\RESEARCH\pattern\fingers\test\*.png';
D = 'C:\Users\USER\Documents\MATLAB\Project\asl_dataset\asl_dataset';
d2 = SelectFile(D,60);   
[Data,Target] = FExtraction(d2);
O = NNTest(net,Data,Target);
disp('recognition rate is : '); 
disp(O);

D = 'C:\Users\USER\Documents\MATLAB\Project\asl_dataset\asl_dataset';

dinfo = dir(D);
dinfo(ismember({dinfo.name}, {'.', '..'})) = [];  %remove . and ..
dinfo(~[dinfo.isdir]) = [];   %remove any files leaving only directories
foldernames = {dinfo.name};

hello walter thank you for answering.. so for this code i just need to add or replace it ?

"So, i want the system can read and call dataset folder name."

It does that part only. It looked to me as if you only wanted to know the names of the folders that were present.

Perhaps you have a different need. Perhaps you want to know, for each file, which folder it came from? That is possible
