Search all files that are NOT one or MORE specific type/extension in a directory

Question

In a folder i want all files except more than one file extension like pdf and html file.
I have already got for single file extension which is

NOT *.pdf  

But In my case I want to exclude two file extension which is html and pdf. What is the way to exclude more than one file extension in windows 7 or Windows *?

Answer 1

You can chain NOT with AND to create multiple conditions.

e.g.

NOT *.pdf AND NOT *.html

This should give you the results you desire.
