I have created a GUI, in that when I add the data from a folder it will load .csv and text files. Now I wanted to add images(.png) lauanch with image viewer from the same directory in app designer.
(Here I have enclosed the example file. i.e It will ask for the select file from the directory after that it launches windows media player with the file.)
But for GUI, without using the 'baseFileName = uigetfile('*.png')' , Is it possible to select from the directory? by using 'uigetfile' it is again asking to select the folder.
for example : it should be like this baseFileName = '*.png'

I do not understand, what you are asking for. Do you want to process all PNGs fils inside a specific folder?
Folder = 'D:\Yor\Folder';
FileList = dir(fullfile(Folder, '*.png'));
for k = 1:numel(FileList)
aFile = fullfile(FileList(k).folder, FileList(k).name);
% Now do what you need with this file
end

This works on my computer:
Folder = 'E:\Movies';
% FileList = dir(fullfile(Folder, '*.mkv'));
FileList = dir(fullfile(Folder, '*.wmv'))
% Not sure WMP plays .mkv files???? Does it?
if isempty(FileList)
errorMessage = sprintf('Error: no video files found in\n%s.', Folder);
fprintf('%s\n', errorMessage)
uiwait(warndlg(errorMessage));
return;
else
fprintf('Found %d videos in "%s".\n', length(FileList), Folder);
end
% Play all videos one after the other.
for k = 1:numel(FileList)
fullFileName = fullfile(FileList(k).folder, FileList(k).name);
% First construct the command line for the system() function.
% Enclose all filenames in double quotes because we may have spaces in the filenames.
arguments = sprintf('"%s"', fullFileName);
commandLine = sprintf('"%s" %s', editorFullFileName, arguments);
fprintf('%s', commandLine);
system(commandLine);
promptMessage = sprintf('Do you want to play the next video,\nor Quit processing?');
titleBarCaption = 'Continue?';
buttonText = questdlg(promptMessage, titleBarCaption, 'Continue', 'Quit', 'Continue');
if contains(buttonText, 'Quit', 'IgnoreCase', true)
return; % or break or continue.
end
end

Try this:
folder = pwd; % wherever you want
% Get a list of all .txt, .png, and .csv files:
fileList = [...
dir(fullfile(folder, '*.txt'));...
dir(fullfile(folder, '*.png'));...
dir(fullfile(folder, '*.csv'))]
% If you want all the names put one cell array:
allFileNames = fullfile({fileList.folder}, {fileList.name})'
% Now files are listed in the order you called dir().
% If you want the list sorted alphabetically:
allFileNames = sort(allFileNames)

You could have the app load the directory files into a dropdown box after selecting a particular file as shown in the example attached.

What version of MATLAB do you have? I created the above in R2022a.
