I would never recommend unzipping files direct to the sim.
thats right, it can lead to all sorts of problems...

what you CAN do to be sure is to check the file pathnames in winzip before doing that
if the PATH field reads something like simply "panel" or "model" then you must create a folder inside the AIRCRAFT folder for your plane
if it reads "planename\model" or whatever, then unzip straight to the AIRCRAFT folder
when in doubt, always unzip to a temporary folder so your files dont end up all scattered
