Haziq = perhaps consider an alternative to recursiveFileList (since you don't have the code for it). See Jonathan Sullivan's FEX submission dir2 for an example of a recursive file "finder".

You can use genpath(). See attached example where it gets a list of all subfolders and then goes into them finding filenames.
