Hi, Our centera client supports saving and retrieving files to/from  Centera.  So  our customer can use this functionality to save and retrieve generated files from our product. As for deletion,  do you think it is better to let our client do the deleting of the clip, instead of let the customer do the deletion with another Centera client, or it doesn't matter -- it can be done either ways. By the way, can two appllications(exe files) using the same pea file?
