    Hi,
    How is it appropriate at this moment to check if a directory/file exists?
    
    I want to use the directory as information on a running-and-restarted 
    workflow, or just start a new workflow and use the given directory name as 
    new store.
    
    So I need sth, like:    <filename> ---> Actor ----> true/false
    
    Is there also a file browser actor somewhere? Or shall I use the 
    FileParameter.
    
    Thanks
    Norbert
