how to export files to specific folders with GUI?

i have a GUI which calculates certain data and exports the data to an Excel file and '.jpeg' file of some plots. Now, what I want to do is to export the result to a specific folder like, "Problem 1" when the program is run for the first time ., "Problem 2" for second time and so on.. so i need a counter for the program and also export the results to specific problems.

Use the fullfile function to build a complete filename (folder + base file name). Here's an example:

% Get the name of the file that the user wants to save.
% Note, if you're saving an image you can use imsave() instead of uiputfile().
startingFolder = userpath % Or "pwd" or wherever you want.
defaultFileName = fullfile(startingFolder, '*.*');
[baseFileName, folder] = uiputfile(defaultFileName, 'Specify a file');
if baseFileName == 0
  % User clicked the Cancel button.
  return;
end
fullFileName = fullfile(folder, baseFileName)

@Image Analyst what i want to do it to save the generated '.jpg' sand '.xlsx' files to a new folder.The folder must be created automatically when the user executes the code . eg: "Problem 1", where '1' is the value of the counter: so for nth execution, the folder name must be, "Problem n"
