Asking the user to enter the extension of the files and load all of them in the current directory

Dear all,

For example, I have many files(.txt, .m and others) in my directory, C:\Users\Kumsa\Desktop\OCM_MAT. I then want the user to enter his/her extension(The user may want to load either .m or .txt files in workspace) and load the files in the similar directory.. Please help me to do that.

If all the files are .txt files, then what's the point of asking for the extension? If you intend to support something other than .txt files, then you need to actually specify what various kinds of files you are going to support.

Answer 1

files = dir('*.txt') ; 
filenames = {files.name}

Answer 2

Folder = 'C:\Users\Kumsa\Desktop\OCM_MAT';
List   = dir(fullfile(Folder, '*.*'));
[~, ~, AllExt] = fileparts({List.name});
AllExt = unique(AllExt);
fprintf('Found file extensions in: %s\n', Folder);
fprintf('  %s\n', AllExt{:});

Now decide how you want to let the user choose one: by input() or in a GUI with a listbox or dropdown menu?

Imprting the files works like this:

List  = dir(fullfile(Folder, ['*', selectedExt]));
Files = fullfile(Folder, {List.name});
for k = 1:numel(Files)
    % import Files{k}...
end
