Hey, with winzip you have one of three options (basic)
1 - Right click the zip/rar files you downloaded, then click extract to folder aircraft....., this will create a folder where the zip download is, you can then just copy over the folder to fs directories
2 - Right click and just extract, this will extrct all files to the directory where the zip is but not put files into a folder with the same name as the zip, in most cases....
3 - Right click the file and click extract too.. a window will open and you can select the fs directory and a folder name you want the files to go into and then it will extract to that folder...
Alot of FS downloads i have tryed recently mostly come with auto extractors or installers....
