Individual file protection on the HP 100/200LX

You can password protect individual files from within the built-in applications (PHONE, APPT, MEMO, etc.), on the HP 100/200LX. With the application and the desired file open, press (MENU) File Password.

Then enter and verify the password. You cannot open this file again without entering the proper password. These passwords are also case sensitive.

To delete the password protection of a file, open it, press (MENU) File Password, and leave the new password empty.

If you use different passwords for different files, keep careful records. Also, with individual password protection the file is actually encrypted. This has two significant side effects: If you forget the password there is no way to recover the file; If the file gets corrupted there is no way to recover the file, even with the password. So, in addition to keeping good track of your password, keep good backup copies of your important files. Robert Roney Editor, HP Palmtop Paper
