FFB was made primarily to block inbound and outbound internet connections of the file types of your choosing. This is accomplished by making multiple new rules in the Windows Firewall at the click of a button. It used to only be able to block .EXE files, but now you may add as many custom file types as you want!
There is also the option to recursively scan though a directory's sub-folders. As well as the option to enable, disable, add and remove user-determined custom file types to the application's scanning process.
FFB is a single lightweight application. I've tried to make the process of using my application as straight-forward and intuitive as possible. Included in the application is an information tab and a FAQ section where some of your questions may be answered.
