Folder Firewall Blocker is a Windows utility that empowers users to block predefined files from sending and receiving data from online sources. This ensures that potentially malicious packages can not cause any harm to the operating system and personal data.

Enhanced security

The software works by configuring custom firewall rules. You can select the target directory by clicking the Search button in the main window. There is a checkbox to include subfolders. Additionally, it is possible to block extra file types besides standard executables such as:

COM;
BAT;
CMD;
VBS and more.

Unlike in Comodo Firewall, users are able to define specific rules for different formats, ensuring that only the intended items are restricted. This is particularly helpful when managing large datasets with multiple suspicious files.

Advantages

As a portable application, Folder Firewall Blocker does not require installation. You can run it directly from any storage device, which is convenient for use across several machines without leaving a footprint. Moreover, the lightweight nature of the program allows for smooth performance even on older PCs.
