Portal Script Format is most often found on 2 operating systems. These systems consist of Mac OS, Windows, although it may occasionally be found on another system, it will be non-functional. The Portal 2 application is recommended to open the file. It was released by Valve Corporation. There are also 3 alternative programs to handle the BNS file. You can use Portal in case Portal 2 cannot be used.
How to open BNS file?
An often recurring problem with Portal Script Format is that BNS is not associated with the correct program file. This is manifested by the fact that BNS files open in unusual applications or do not have an assigned program. This can be quickly resolved by following the instructions below.
The first thing you should do is just "doubleclick" on the BNS file icon you want to open. If the operating system has an appropriate application to support it and there is also an association between the file and the program, the file should be opened.
Step 1. Install Portal 2
The first step is to check if the computer has the Portal 2 program installed. To do this, enter the name Portal 2 into the system search engine. If we do not have this program, it is worth installing it, as it will help you automatically associate the file BNS with Portal 2. Later in this article you will find a list of programs that can open BNS files.
Programs to open BNS file
Remember to download programs supporting BNS files only from verified and safe sources. We suggest using the websites of software developers.
Step 2. Create association of Portal 2 with BNS files
However, it may happen that the application itself does not cause the BNS file to open in the Portal 2 application, but you can set it manually. This option is available from the level of Properties of a specific file available in the context menu. Information about the file and the program that the file is associated with are available here. Changes can be made using the "Change" button. If there is no software on the list, simply select "Browse" and manually select the directory where the application is installed. Checking the "Always use the selected program ..." box will permanently associate the BNS file with the Portal 2 program.
Step 3. Update Portal 2 to the latest version
If, however, after binding Portal 2 with Portal Script Format there were still problems, you should update the program to the latest version. Some applications allow you to update from the program level, and for others you need to download the installer from the Valve Corporation page and install.
Step 4. Check for the following problems with the BNS file
If the above steps do not help, you can assume that the file itself is not correct. The most common file problems are:
The BNS file may be unusually small compared to the original file. This suggests truncating the BNS file contents when downloading or copying. The only repair option is to download the file again.
The computer may have fallen victim to a computer virus or hacker. A quick virus scan using an up-to-date antivirus program should clear up any doubts. Alternatively, you can use the scanners available online. The scan should cover the entire computer, not only the BNS file that we want to open. As a result of the scan, sometimes it is not possible to recover BNS files, which are deleted if there is a backup of this file, then after restoring it, it must also be scanned.
Older version of BNS file may not always be supported by the latest software version. On their websites, developers usually offer free solutions to such problems, e.g. in the form of a conversion program or an older version of the program.
The file may be corrupted in a number of ways. The repair method must be adapted to the type of file and damage. Some programs offer the option of recovering data from damaged BNS files. The easiest way to restore the file is from a backup or by contacting Valve, but this one can be expensive. Not all damage can be reversed.
When reading, a message appears that the file was encrypted or corrupted. The encrypted BNS files cannot be played on other computers than the one on which they were encrypted, they must be decrypted before using on another device.
Some of the system directories are excluded from modification. While there is usually no problem reading such a file, it may not be possible to save it. Copying the BNS file to another location will fix the problem.
This can happen on a file that does not support multiple access. In this case, the BNS file is blocked by the first application to open it. Closing other programs should help. Sometimes you have to wait for the session to the file BNS to close. Some anti-virus or backup software may occupy the BNS file for a certain period of time. If the problem persists, restart the machine.
