- On a technical level, you can simply set the invisible bit with ResEdit.
- I don't know if the Control Panel will read invisible files, but it might
- work. However, DON'T DO THIS. It's not enough copy protection to be
- useful, and it's guaranteed to make paranoid people like me on edge. If
- I install a program, and it starts writing invisible files over my hard
- drive, I'll want to know why, and don't think that making them invisible
- will cause trouble for anyone with enough knowledge to reverse engineer it.
-
- If you do something sneakier than just setting the invisible bit, odds
- are it will set off my virus software. Most users, myself included,
- won't let a program do something mysterious to their disk w/o panicking.
-
- If you want copy protection, use a Dongle, use a key-disk, or use one
- of those little code wheels, but don't try this. It won't stop copying,
- and it will freak your buyers.
