yup... the filenames aren't encrypted in ZIP so that they can be properly
extracted... encryption of ZIP files does not mean that the whole archive is
encrypted... only that the data of the files is...

winzip? what about plain old original pkunzip? then there's the infozip
packages and numerous others... if you have software that is able to encrypt
the filenames, i dare say that it won't be able to be unpacked without problems
of some sort on other systems using other archivers that can handle zips...

    Sorry for the very late reply. I stopped watching the group.
    Right click, add to 7z archive, choose a password, encrypt.
    7z archive will only be opened if you enter the correct
password, so there is no way you can see the original filename.
    Both Winzip and Winrar open 7z archives.
