Windows XP + SP2. Media Center version - I don't know, but it doesn't matter anyway. Since Windows 2000, WIndows Explorer can do some basic zip archive handling; it can open a zip archive in a separate window and let one browse the archive like one browses directories on disk. If the zip archive is created with BetterZip (compatible one, no Mac specific stuff), Windows Explorer zip handler shows EVERY directory in the archive as a double entity: a directory itself, but also some "mistiqye" file of the same name as the directory, 0 bytes big. An attempt to extract those files ends with error message "The system cannot find the file specified".

WinZip and WinRAR don't show this strange files, which are apparently, not in the archive at all.
