Hi David!

1) The Windows Explorer has problems to create such files, but it is perfectly possible
    to create such files if you use "correct" (say "unbuggy") software. ;-)
    Another point is, that it is useless to create a .knoppix file under windows since
    it's important that there is an ext2 filesystem inside of .knoppix. Windows can't do this!
    (Under Linux there is the script "knx_persistent_home" in the persistent home bundle, that
     creates the correct file for you).

2) Persistent home searches the partitions read-only. When it finds its .knoppix file it mount
     resp. remounts the partition as read/write.

This should work as far as i know!

I like the name, because a) it does not get in your way under linux (hidden by default)
and b) it has a special "extension" under windows so that you don't open it by mistake.
You can however easily delete the file under Windows to get rid of your persistent home
(if you need the space on your usb pen drive).

Its already done.

:-) Don't do that :-)
