Hello community,

I have a simple problem. I want to prompt the user to enter a directory name, check if it exist. If it does, store that fullpath into my guidedata. If it doesnt, create the directory and also 2 subdirectories within that directory then store fullpath into guide data. The name of the directory I want to search and create folders in is named 'Labelers.' It's fullpath is C:\Users\ecorbett\Documents\MATLAB\Labelers So far I have this code:

prompt = {'Enter Labeler Name:'};
dlg_title = 'Labeler Name';
num_lines = 1;
answer = inputdlg(prompt);
if isempty('Labelers'(answer))
     mkdir('Labelers','answer')
else
    handles.name = answer;
    guidata(gcf, handles);
    handles = guidata(gcf);
end

It's not working thus far. Any advice will be greatly appreciated!

Why don't you just call uigetdir to let the user specify a folder and create one if needed? The "New folder" button is right there on the dialog box.

Hmmm, hadn't considered that option. I suppose that would have been easier.

在 MATLAB Online 中打开

root = 'C:\Users\Oleg\Desktop\';
answer = inputdlg(prompt);
if isempty(answer{1}) || exist([root answer{1}],'dir') ~= 7 
     mkdir(root,'answer')
else
    handles.name = answer;
    guidata(gcf, handles);
    handles = guidata(gcf);
end
