filebizz.com is a valuable domain it's extension is .com
The word filebizz is unique for google search. It's useful to make online platforms like tech news portal, data or content related sites and relevant for many other related categories.
Bizz is not a great keyword based on my research on NameBio. Hence, I see this name as something that has a mid $$$ potential but if it doesn't sell the first year, I think you should drop this off.
