Hello
I have an old code using uigetfolder but when I run it I have error message: The function UIGETFOLDER only works on a MS-Windows PC. I wonder if I can use uigetdir to fix it or maybe there is beter way?
function folder = uigetfolder(title, initial_path)
%UIGETFOLDER Standard Windows browse for folder dialog box.
%
% folder = uigetfolder(title, initial_path)
%
% Output: folder = selected folder (empty string if dialog cancelled)
% Inputs: title = title string (OPTIONAL)
% initial_path = initial path (OPTIONAL, defaults to PWD)
%
% Examples: folder = uigetfolder - default title and initial path
% folder = uigetfolder('Select results folder') - default initial path
% folder = uigetfolder([], 'C:\Program Files') - default title
%
% See also UIGETFILE, UIPUTFILE
%-----------------------------------------------------------------------------------------------
if ~strcmp(computer, 'PCWIN')
error_dialog_handle = errordlg(['The function ', upper(mfilename), ' only works on a MS-Windows PC'], ...
mfilename, ...
'modal');
folder = '';
else
if nargin < 2
initial_path = pwd;
end
if nargin < 1 | isempty(title)
title = 'Select a folder';
end
% Error checking
if ~ischar(title)
error('The title must be a string')
end
if ~ischar(initial_path)
error('The initial path must be a string')
end
if ~exist(initial_path, 'dir')
error(['The initial path: ', initial_path, ' does not exist!'])
end
folder = uigetfolder_win32(title, initial_path);
end
%-----------------------------------------------------------------------------------------------

Wow I looked up this function on FEX and its last update was in the year 2000 (so its pretty much ancient). Like you said yourself, uigetdir(path, title) will work just fine (which was introduced in R2006a). Just remove the error_dialogue part en change uigetfolder_win32 to uigetdir.
function folder = uigetfolder(initial_path, title)
%UIGETFOLDER ^please note that I changed the position of initial_path and title; makes more sense
if nargin < 2
initial_path = pwd;
end
if nargin < 1 | isempty(title)
title = 'Select a folder';
end
% Error checking
if ~ischar(title)
error('The title must be a string')
end
if ~ischar(initial_path)
error('The initial path must be a string')
end
if ~exist(initial_path, 'dir')
error(['The initial path: ', initial_path, ' does not exist!'])
end
folder = uigetdir(initial_path, title);
end

Ah I see, change
isempty(title)
by
exist('title','var') == 0
and it should be fine
Thank You for your quick answer! Everything is working fine ;)
