I would like to help you, but I don't really think you can afford an international call to Italy only to have the honor to decipher my spoken english.

I don't really get your problem though. When you install planes, the best thing to do is to extract the main zip file in a temp folder, then put the folder inside with the model, panel, sound and dynamics of the plane into the "aircrafts" folder of FS9, then look for other subfolders into the temp folder.
If there is a folder named "gauges", you'll take the files inside it and move them into the "gauges" FS9 folder. If there's a folder named "effects", you'll take all the files inside and move into the FS9 "effects folders", and so on. Sometimes the effects can be inside a zip files, sometimes even the gauges, instead of a subfolder, but that's quite straightforward, treat the content of the zip files like they are folders themselves and you'll be fine.
A good idea is to always look and follow the instructions of the readme file, to see if there are exceptions or special requirements. If exceptions or requirements are contemplated, then follow the writ on the readme file and you should be fine.
If the problem is instead the use of windows to manage and move files, well then, you don't have a problem with FS9, your problem is with windows. It would help in moving files around if you set winXp to display icons and windows "the old way". The old way being the easy and intuitive way of using windows that M$ inherited in Win95 from the Mac and that (just for the sadistic pleasure of complicating the life of the users) has tried to leave behind with Xp and its absurd default displaying of the start menu and absence of utility icons on screen. But that's just another mess, and if this is your problem it would be a good idea if you found someone that can teach you how to use windows.
There's but one real cure for human stupidity. It's called DEATH.
At the moment mourning the assassination of sarcasm and irony for the good of the "higher".
