If you downloaded Flash from macromedia's site it's most likely a single file with a tar.gz at the end of it correct? If so, it's best to know what that tar.gz actually is.
Unlike "winzip" and "winrar" *nix Operating systems store and compress files differently. *nix OSes are known best for being "a collection of small applications that do one thing and one thing right". In this case, the packing and compression of the file are two different programs (steps). YOu use one program to pack all the files into a single file and then another program to compress the one file.
These two steps usually use the following programs;
tar: tar takes a collection of files and creates a single file or 'tarball' out of them. This makes it eaiser to move and manage the files.
gzip: gzip is a compression program that takes a file and compresses it, very much like Winzip or Winrar for Windows. So once you create a tarball, the best thing to do is to compress it, using gzip, to make the file size smaller.
files with an appended "tar.gz" mean that it's tarballed (tar) and compressed (gzip)
Now im assuming you have a Graphical User Interface (GUI) and with that, comes a bunch of programs that make this process very easy to do but lets not go that route, Im going to teach you how to do this by hand, as it will get you familiar with the operating system at a more powerful and personal level.
First and foremost, you need to understand how to navigate through directories and files in the console. Do you know how to do this?
(look in your book you jsut bought and look up topics related to 'console navigation' or 'cd' 'ls' 'mv' 'cp' 'view' and reply back to this thread.)
