will be saved in the Password property and it will also be returned as 
result."
However, just by calling this function, the password will not be 
automatically saved in the Password property. It continues to ask for a 
password for every file in the archive!

_2. Bug when extracting zero-byte files from an encrypted archive:_ When 
attempting to extract zero-byte files from an encrypted archive created 
by ZipMaster the following errors occur:
a) Zero-byte files with no extension will be extracted as 12 byte files 
with "random" bytes.
b) Zero-byte files with ".txt" extension will not be extracted at all.

However, when the same encrypted archive is extracted with 7-zip no 
errors occur.
However, 7-zip does not extract zero-byte files with no extension.

But, when the same encrypted archive is extracted with DOpus, most of 
the files inside the archive will not be extracted at all!
So there seems to be a sort of incompatibility with the PKZip standard 
in ZipMaster?
