Disky Business by Jeff Holbrook is a pretty simple set of utility functions for dealing with basic floppy disk tasks on a Commodore 64 with a 1541 floppy drive.  A couple features I like about this program are that it works with drives other than just device #8 and that it has the ability to move a file on the disk into the first position for using load "*",8,1.  The program has many other abilities which you can see in the screenshots.
