Surely this is what recursion does for you?

e.g.

function directoryTreeAsArray tRoot, tSubPath --> aTree
    local aTree
    set the defaultFolder to tRoot & "/" & tSubPath
    put the files into aTree["files"]
    repeat for each line f in the folders
       if char 1 of f = "." then next repeat -- unix gotcha
       put directoryTreeAsArray(tRoot, tSubPath & "/" & f) into 
aTree["folders"][f]
    end repeat
    return aTree
end directoryTreeAsArray

(initially invoked with empty second parameter)

Or have I misunderstood the requirement?
