I just downloaded a bunch of new planes for CFS1. Most of them unzip just fine into the aircraft folder. Unfortunately some of them (eg ju-188) unzip to show a huge bunch of files that aren't in any particular order or folder. I'm used to being able to unzip an aircraft and it comes up as the usual panel, sound, texture etc folders that go nicely into the aircraft folder in CFS. But what do I do with these???

Unfortunately zipfiles are not all configured in the same way & come in all shapes & sizes. If you're using WinZip make sure the "Use folder names" option is checked. Use the right-click "Extract to folder ........." option to extract the files. This will automatically extract them as they were originally configured into a new folder with the same name as the zipfile in your download directory. Never unzip downloaded zipfiles direct to the sim. This is the most common cause of installation problems.
