Hi guys,
I am trying to list all the files i have inside a folder but i am having some difficulties. First of all, i listed the names of all the folders i have inside that directory. Now, i am trying to list the files within those folders. I used the code bellow but it´s not working :X
handles.diretorio='H:\Tese\ferramenta\excel\';
handles.lista=dir(fullfile(handles.diretorio));
handles.C=get(handles.popupmenu5,'String');
handles.C=handles.lista;
handles.listaC=dir(fullfile(strcat(handles.diretorio,handles.C)));
Can anyone help?

You can use genpath(). That's what I do in my attached demo. It will recurse into all subfolders and find the names of all the files in all those folders.

Try this code. I changed it a bit and it's attached again.
% Start with a folder and get a list of all subfolders.
% Finds and prints names of all files in
% that folder and all of its subfolders.
% Similar to imageSet() function in the Computer Vision System Toolbox: http://www.mathworks.com/help/vision/ref/imageset-class.html
clc; % Clear the command window.
workspace; % Make sure the workspace panel is showing.
format long g;
format compact;
% Define a starting folder.
start_path = fullfile(matlabroot, '\toolbox');
if ~exist(start_path, 'dir')
start_path = matlabroot;
end
% Ask user to confirm or change.
uiwait(msgbox('Pick a starting folder on the next window that will come up.'));
topLevelFolder = uigetdir(start_path);
if topLevelFolder == 0
return;
end
% Get list of all subfolders.
allSubFolders = genpath(topLevelFolder);
% Parse into a cell array.
remain = allSubFolders;
listOfFolderNames = {};
while true
[singleSubFolder, remain] = strtok(remain, ';');
if isempty(singleSubFolder)
break;
end
listOfFolderNames = [listOfFolderNames singleSubFolder];
end
numberOfFolders = length(listOfFolderNames)
% Process all image files in those folders.
for k = 1 : numberOfFolders
% Get this folder and print it out.
thisFolder = listOfFolderNames{k};
fprintf('Processing folder %s\n', thisFolder);
% Get ALL files.
filePattern = sprintf('%s/*.*', thisFolder);
baseFileNames = dir(filePattern);
% % Get m files.
% filePattern = sprintf('%s/*.m', thisFolder);
% baseFileNames = dir(filePattern);
% % Add on FIG files.
% filePattern = sprintf('%s/*.fig', thisFolder);
% baseFileNames = [baseFileNames; dir(filePattern)];
% Now we have a list of all files in this folder.
numberOfImageFiles = length(baseFileNames);
if numberOfImageFiles >= 1
% Go through all those files.
for f = 1 : numberOfImageFiles
fullFileName = fullfile(thisFolder, baseFileNames(f).name);
fprintf(' Processing file %s\n', fullFileName);
end
else
fprintf(' Folder %s has no files in it.\n', thisFolder);
end
end
