Using only mime types for files when expanding doesn't work in Haiku's Expander. It does in original. Try to remove the file extension and open in Expander. Works in original, but not in replacement. When "Show Contents" is checked and dropping a file on the window, it doesn't update to the contents of the new file. Original Expander updates the contents instantly. Jerome, I saw in your update to the CVS that you had changed the extracting command (from -xvf to xf I think). I was talking about the listing command (-tvf to -tf)... Best regards Fredrik Ekdahl
