I have some ZIP files which return "Unsupported method" on directories inside the archive.
WinRar does not return any errors on these files.

I'm running win 7 x64 and 7-Zip 9.30 alpha.

Here are some small example files
ut-files.com/index.php?dir=Maps/Assault/&file=AS-biux.zip
ut-files.com/index.php?dir=Maps/Assault/&file=as-eiffel.zip
ut-files.com/index.php?dir=Maps/Assault/&file=as-holygrail.zip
ut-files.com/index.php?dir=Maps/Assault/&file=as-pollux.zip
ut-files.com/index.php?dir=Maps/Assault/&file=as-submergine.zip

    This archive has errors in central directory header.
    All directory entries in central directory header use the reference to same local entry (first root entry).

    Igor, glad communicate with you! First - many thanks for your great 7Zip! First - it's really a bug in 7Zip when unpack xxx.xxx.xxx.ext files from ZIP archives. When unpack from RAR or 7Z archives - it's all right. Check please.

    a little addition. no matter with dots in file names (being packed). when create archive with 7zip - no problem with pack and unpack. only when try to unpack zip downloaded from google photo albums for me.

    Hi!

    I get the same message on this ZIP too:
    http://tin.at/software/vbrun100.zip

    Is it a very old ZIP-format, or does it also contain an error?
