What folders of files?
There are no folders you have to download.
What single package do you expect? It's not a single package
-- it's "scratches" you have to build your system from.
To get it straight
:
1. Read the
LFS book, the book is good (=RBBG)
2. Download the packages from p. 3.2
3. Follow the book and build everything - get the core system
4. Start thinking about BLFS, HLFS or whatever
Good luck!!!
