I would like to create a code that creates a folder, verifies if it already exists and if it occurs asks the user if continue or not.

If the folder already exists, two options should be available:

overwrite the folder (delete it and remake)
terminate the code

My code is:

name='Folder';
loadcase='11';
if ~exist([name,loadcase], 'dir')           % create saving folder
    mkdir([name,loadcase]);
else
    prompt=('The folder already exists. Do you want to overwrite the analysis?');
    risp=input(prompt,'s');
    if risp=='Y'
        rmdir([name,loadcase]);
        mkdir([name,loadcase]);
    else
        finish        
    end
end

Probably what to put in in place of finish

If you were to put this into a function then return from the function.

It doesn't work for non-empty folders

As the documentation states, rmdir only works for empty folders. If you want to remove all files and folders inside that folder you will have to use the s switch:

rmdir([name,loadcase],'s');

doc:

rmdir folderName s also attempts to remove all subfolders and files in folderName, regardless of their write permissions. The result for read-only files follows the practices of the operating system.
