Re: How can I check if a folder is empty in bat file?

Having sync'd my newsgroups it seems you'd already found that one ... or
a close derivative!

I've since taken another look at using the "if" statement to achieve
your goal and found many other way to get there, none of which use "if"
exclusively ... there may well be a creative way but I've yet to find it
I'm afraid!

Sorry ... Dean
