Is it possible to provide a view of list  of documents  from a specific  folder
from one document library in a sub site?



I have tried the default web part coming with MOS-2007 named: "Content Query
Web part", which can do query to the content of the list not to the content
of the folder.

For this you can make a custom webpart  that will be able to list  all the
files and also the files in the sub folder  of that document library.
If required I can give the sample code for the same but first try your self.

I am not so familiar with customization and development of the web part. I
am covering only the administration side of MOSS 2007.

It is possible and the quickest way is to make a custom webpart  for your
requirements.

So give the exact requirements so i can help u out.
