you want directories? really?

Some sort of hierarchy is usually implied by the work at hand, but making that happen can also be at the human level rather than at the machine level. I work on a platform with a flat file system and we use naming conventions to organize things. I don't know what you consider medium-big but there are certainly many very large projects done without (and well-before) UNIX or Windows-style filesystems.

OTOH (and I am not a Prime owner) I do like the HP 48's directories. It helps me organize things more quickly than most other ways I could think of, given that it's a calculator. On a machine with a full-size qwerty keyboard I wouldn't like having a directory tree to deal with but on a small device I agree with what I think you are saying, it's nice having a directory tree.

I don't know that it's harder to find things in either type of file system as long as the system has good search and find tools or if you can write them yourself.

Yes. I would have liked the ability to make a subdirectory read-only on the HP 48.
