Hello, The value of n is initialized in the main procedure which
calls it. Basically I am trying to find the n'th file in the directory(can
be in its sub directories too). As I've given the previous mail itself
file = findFile(path)
invokes that function.When the path is a
directory it just recurses into it. And coming to your idea of storing all
the items in a list can't be used here because my folder contain thousands
of files and storing them in a list would eat up my memory.
Thanks for your suggestions,
Venu
