What is the best way to test whether a drive exists? Sometimes the Dir("C:")
returns "" even when the drive is completely valid.

Maybe I should do ChDrive then test Err.Number. Then ChDir then test
Err.Number???

When I call the function Dir("Q:\") and Q:\ is a network mapped drive does
it fail (return "") if it does not receive a reply within a certain
time-limit? The reason why I ask is because the update response from a
network mapped drive is very slow here. If the slow response causes
Dir("Q:\") function to return "" then how can I make it longer time-out?
