[BioC] Applying bioconductor functions to files in different Windows directories

            I would be grateful for any help or advise on the following issue.
I have affy files in different directories and want to point ReadAffy() to read files from all directories. 
Is there a way I can do this via setwd but in a loop and if so how?
For example can I say :

setwd("C:\\RawArrayData\\Cel Files\\U133\\*")
X <- ReadAffy()
Also similarly, I wrote a function that annotate files in separate directories. Can I run that on the root and get it to annotate all files below 
the root directory in windows i.e. the children of the root directory.
Many Thanks,
Imagine a life without walls.  See the possibilities.
