I'd like to find a sub-folder in the currend directory. If not exist creat it. I tried to use if ~exist(,'file') but this search in other folders too, and find a sub-folder with the same name in other folder, but in the current directory not exist that sub-folder.

You can specify exist to only look in the current directory. For example:

lFolder = 'MyFolder';
if(exist([cd filesep lFolder]) == 7)
    disp('Folder found!')
end

Prefer fullfile to consider if cd replies e.g. 'c:\'.

if exist(fullfile(cd, lFolder), 'file') == 7

Calling exist(name) without 2nd input is critical: It replies 1 if a variable with this name is existing. Therefore exist should be used with the specifier of what kind of object you are searching in general.
