How to open IW4 file?

The main problem with DjVu Image Format is that the IW4 file is incorrectly associated with programs. This causes the file IW4 to open by system applications not designed for this purpose, or to display a message that there is no associated program. How to solve such a problem?

The first thing you should do is just "doubleclick" on the IW4 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 DjVu Solo

The first step is to check if the computer has the DjVu Solo program installed. To do this, enter the name DjVu Solo into the system search engine. If it is not, installation may solve the problem, as most applications create file associations during installation. Below is a list of programs that support the file IW4.

Programs to open IW4 file

Remember to download programs supporting IW4 files only from verified and safe sources. We suggest using the websites of software developers.

Step 2. Create association of DjVu Solo with IW4 files

However, it may happen that the application itself does not cause the IW4 file to open in the DjVu Solo application, but you can set it manually. 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 IW4 file with the DjVu Solo program.

Step 3. Update DjVu Solo to the latest version

If, despite the association of the DjVu Solo program with the DjVu Image Format file, the file still does not open, check the program version and possibly update it to the newest version. In this case, use the LizardTech, Inc. website or update the program from the application.

Step 4. Check for the following problems with the IW4 file

Of course, it may happen that despite the above steps, the file still does not work. The most common file problems are:

The IW4 file may be unusually small compared to the original file. This is most often caused by a problem while downloading the IW4 file. The file should be downloaded again, making sure that the process has finished correctly.
The computer may have fallen victim to a computer virus or hacker. Perform a virus scan using available and up-to-date anti-virus software. If this is not possible, you can use the online scanner. However, it is important to scan the entire system, not only the file IW4 or the program directory. Sometimes virus-infected IW4 files cannot be recovered, so make a backup in advance.
A typical compatibility error - the program does not support the older version of the IW4 file. Help should be sought from the software developer, as they usually recommend using free file converters or installing an older version of the program.
There can be many reasons for this. The repair method must be adapted to the type of file and damage. Some programs offer the ability to automatically repair IW4 file corruption. You can restore the file from a backup or use N/A help.
The program indicates that the file is encrypted or corrupted. The encrypted IW4 files can be used by the device on which they were encrypted, on any other device it is required to have the appropriate cryptographic key and decrypt the file before its recovery.
The operating system protects files in some locations (e.g. the root of the system partition) against unauthorized access. These directories are write-protected to them and it's very hard to fix this problem. It is best to move IW4 to a different directory.
This problem only occurs with more complex files. You may find that another program you are using is preventing you from working with the file. Closing other programs should help. Sometimes it is necessary to wait a while before referencing the IW4 file again. Antivirus programs or a backup being made may lock the file for a while without the user's knowledge. If nothing helps, please reset the device.
