We don't keep program's by number. We store ours on our PC saved as the drawing number. That way we only have max 3-4 programs in the machine at any one time. Depending on number of operations. Whether we use CAM to produce them or write then longhand on the machine we do the same. As soon as the job is finished, if the program's are old proven jobs we dump them, if they are new and have just been proven for the first time we send them back to the PC and save them in their own drawing number file with revisions, op numbers etc. that way you can stick in any other info to that part file you like setup pics etc. makes it easier to find them next time too, just search for the drawing number and hey presto.
