[news.eclipse.technology.equinox] Equinox p2

[<madalina_2311@xxxxxxxxx>]

Hello,
I have an Eclipse based product (i use sdk 3.4.1) that has the following content:

eclipse/
    configuration/
    dropins/
    features/
    jre/
    p2/
    plugins/
    readme
folder1/
folder2/

In folder1 i have :
 subfolder1
 subfolder2
 a1.pdf
 a2.pdf
 b1.dll
 b2.dll

How can i make my Eclipse p2 see folder1 as having files and subfolder that should be updated?
If it is possible (as i read in p2 documentation), how will i be able to add updates on a site(until now i could only add features) for folder1 and its structure?
Sorry for my trivial questions, but I've just started to learn about the P2 updater.

Thank you,
Madalina
