Never type another pathname.

Apple gave the //e a filer, and it works. You simply have to know where everything is before you start, and type it out from memory, one slash at a time.

ZipFiler shows you. Two directories, side by side, and the cursor keys to pick from them. A pathname never has to be typed — not to copy a file, not to move one, not to go three levels down.

The left panel is where things come from and the right is where they go. S swaps them over when you want it the other way round. That is the entire model, and there is nothing else to learn.

Commands are single letters, because a file manager you use every day should not ask you to hunt through a menu for the thing you do most.

Tag a batch of files using the space bar and a command will process the lot. Tag nothing and it acts on the line the cursor is on.

Copying a directory brings its contents, and everything below them. It is written flat rather than recursively — one directory open at a time, with the way back on a small stack — because the //e has 128K and a deep tree should not be the thing that runs it out.

Catalogs are read into memory once, so moving the cursor costs nothing and the disk stays quiet until you ask it for something. Nine thousand bytes of 6502 assembly, and no runtime under it.

Press RET on a program to run it, whether it's a SYS file, a BIN or a BAS program — which ZipFiler starts BASIC.SYSTEM for and hands the name to, so it runs rather than dropping you at a prompt.

Press P and you'll see PR#. Type a number to boot that slot.

And if you like, quitting can come back to ZipFiler. A small patcher on the disk replaces the ProDOS quit routine on any volume you choose, so leaving any program returns you to ZipFiler instead of the default selector. The original config is kept, and the patcher can put it back at any time.

Your authorized Apple dealer will not be able to help you with any of this. There is, instead, a download button.
