No, a directory starting with a ! is "magic". It could contain a !boot file (what to do when the filer sees the directory for the first time), a !run file (what to do when the directory is double clicked), a !sprites file (containing the icons, which can also used for the directory itself). See http://www.guidebookgallery.or... for an example.
I live in Mexico, and coincidentally I wondered about the crazy price of hearing aids when at Costco last week. 20,000+.. 50,000+ which translates to 1.147 USD.. 2.867 USD. No idea how good those are compared to the USA.
Much better is to use a longer pass phrase that you can remember, for example "Silly AC ate a horse staple battery on Slashdot (/.) for breakfast after a severe asthma attack!". And no, that's not the phrase to access my luggage.
