Hi, I was wondering if you could help me change the folder when the pushbutton is clicked?

For example, my current folder is C:\Users\Valued User\Documents\5th year, 2nd term\THESIS on which all my files are on.

However, I want it that when I push my "load image" button in my gui, the browser would go directly to another folder inside my current folder which is C:\Users\Valued User\Documents\5th year, 2nd term\THESIS\imagesss.

In short, I want the browser to open directly in a specific folder when that button is clicked. Is there a good way to do this? Here's the code which is available in the internet by the way:

% --- Executes on button press in pushbutton1. function pushbutton1_Callback(hObject, eventdata, handles) % hObject handle to pushbutton1 (see GCBO) % eventdata reserved - to be defined in a future version of MATLAB % handles structure with handles and user data (see GUIDATA) %cd('C:\Users\Valued User\Documents\5th year, 2nd term\THESIS') %pwd('C:\Users\Valued User\Documents\5th year, 2nd term\THESIS\imagesss')

%----------> here we load image

global im im2

[path,user_cance]=imgetfile();

if user_cance

    msgbox(sprintf('Error'),'Error','Error');
    return
end
im=imread(path);
im=im2double(im); %converts to double
im2=im; %for backup process :)
axes(handles.axes1);
imshow(im);

If it works like uigetfile, you should be able to pass the desired folder as an argument,

 [path,user_cance]=imgetfile('C:\Users\Valued User\Documents\5th year, 2nd term\THESIS\imagesss\');

If this does not work you may need to go around it by changing the folder temporarily.

 workPath = pwd;
 cd('C:\Users\Valued User\Documents\5th year, 2nd term\THESIS\imagesss')
 [path,user_cance]=imgetfile();
 cd(workPath)

I tried putting it but still it opens not in the destination i want it to go to :(

global im im2
workPath = pwd;
 cd('C:\Users\Valued User\Documents\5th year, 2nd term\THESIS\imagesss')
 [path,user_cance]=imgetfile();
 cd(workPath)
if user_cance
    msgbox(sprintf('Error'),'Error','Error');
    return
end
im=imread(path);

Are you sure that the path is correct? Try running just the cd(...) line to check if it works.

Otherwise, do you know the file format of the file you will open? In that case, try using uigetfile instead of imgetfile. For a png-file, it would look like this:

 [FileName,PathName] = uigetfile('C:\Users\Valued User\Documents\5th year, 2nd term\THESIS\imagesss\*.png')
 user_cance = ~ischar(FileName);
 if user_cance
  ...
 end
 path = fullfile(PathName,FileName);
