Excellent tip out there!

one question!
is this file protected from software like unlocker too??

Hi Ron

I tried...fine, fine, fine. This works just fine.
But it seems only the "lpt1" stays put and if I create in another name I can delete it without any probs
I mean right from the explorer...Why is that? can you please throw more light on this one

 :)Thanx a lot Ron.. I used your tip in Vista - works fine...Now I'm moving my important files there

This can be done  for LPT1 and similar names in DOS

as these are DOS internal keywords

i.e. these names LPT ..., and other similar names from DOS

LPT  is Port name generally given and used for Printer (can refer to Configuring Printers in DOS 6.22)

Like wise COM is also a port name for COM devices it also not delete able and rename able.

Thx

Thanks Ron. It works like a charm
