How to open EFW file?

The most common problem when using Renamed Zip Or Executable Format is that a specific EFW is not associated with the program. This causes the file EFW to open by system applications not designed for this purpose, or to display a message that there is no associated program. This can be quickly resolved by following the instructions below.

The first thing you should do is just "doubleclick" on the EFW 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 BOMArchiveHelper

The first step is to check if the computer has the BOMArchiveHelper program installed. This can be achieved by typing BOMArchiveHelper into the operating system search engine. If it is not, installation may solve the problem, as most applications create file associations during installation. Below you will find a list of applications that support EFW files.

Programs to open EFW file

Remember to download programs supporting EFW files only from verified and safe sources. We suggest using the websites of software developers.

Step 2. Create association of BOMArchiveHelper with EFW files

If, despite the installed application, the EFW file does not start in the BOMArchiveHelper application, you must create a file association. It is most convenient to call the context menu with the right mouse button and select Properties. Information about the file and the program that the file is associated with are available here. Using the "Change" button we can set the program to handle this type. 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 EFW file with the BOMArchiveHelper program.

Step 3. Update BOMArchiveHelper to the latest version

The fault may also lie with the BOMArchiveHelper program, it is possible that Renamed Zip Or Executable Format requires a newer version of the program.

Step 4. Check for the following problems with the EFW file

Of course, it may happen that despite the above steps, the file still does not work. File problems can be divided into the following:

The affected file may be 0 KB or smaller than expected. This suggests truncating the EFW file contents when downloading or copying. Downloading the file again should fix the problem.
The operating system may be infected with a computer virus. A quick virus scan using an up-to-date antivirus program should clear up any doubts. If this is not possible, you can use the online scanner. However, it is important to scan the entire system, not only the file EFW or the program directory. Sometimes virus-infected EFW files cannot be recovered, so make a backup in advance.
A typical compatibility error - the program does not support the older version of the EFW file. 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.
There can be many reasons for this. Repairing is very dependent on the file type. Some programs offer the ability to automatically repair EFW file corruption.
The program indicates that the file is encrypted or corrupted. The encrypted EFW 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. These directories are write-protected to them and it's very hard to fix this problem. If possible, you can try to move the EFW file to another location.
This problem only occurs with more complex files. In this case, the EFW file is blocked by the first application to open it. Just close unnecessary programs. If the error persists after closing other programs, wait for a while. Some anti-virus or backup software may occupy the EFW file for a certain period of time. If the problem persists, restart the machine.
