What is SUNIFF file?

The file in the SUNIFF format belongs to the Raster Image Files category. It was designed by Sun Microsystems. In addition to this file, the Raster Image Files category includes 522 related files. Sun TAAC Image appears on 3 operating systems as a functional file. Although it can be found with greater or lesser success on any operating system, it will only be useful on Linux, Mac OS, Windows. The main program that supports this format is XnView. This was created by Pierre-Emmanuel Gougelet. This file type can also be opened by 3 other programs. SunOS will apply when it is not possible to use XnView.

How to open SUNIFF file?

The main problem with Sun TAAC Image is that the SUNIFF file is incorrectly associated with programs. Thus, when you open SUNIFF, the program selection wizard or some other program starts. This can be quickly resolved by following the instructions below.

The first thing you should do is just "doubleclick" on the SUNIFF 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 XnView

In this case, you should first verify that the XnView application is installed on the computer. This can be achieved by typing XnView into the operating system search engine. If we do not have this program, it is worth installing it, as it will help you automatically associate the file SUNIFF with XnView. Below you will find a list of applications that support SUNIFF files.

Programs to open SUNIFF file

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

Step 2. Create association of XnView with SUNIFF files

If the application is or has been freshly installed, but the SUNIFF file still does not use the XnView program, it means no 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 SUNIFF file with the XnView program.

Step 3. Update XnView to the latest version

If, despite the association of the XnView program with the Sun TAAC Image file, the file still does not open, check the program version and possibly update it to the newest version. In this case, use the Pierre-Emmanuel Gougelet website or update the program from the application.

Step 4. Check for the following problems with the SUNIFF 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:

Very often, the file may be size 0 or incomplete. Usually this applies to SUNIFF files downloaded from the Internet in case the download did not finish properly. 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. For the best results, we will scan the entire operating system, not just our SUNIFF file. However, remember that not every infected SUNIFF file can be recovered, so it is important to take care of regular backups.
A typical compatibility error - the program does not support the older version of the SUNIFF file. These problems are known and are often very easy to fix using the software developers's website.
There can be many reasons for the failure. The repair method must be adapted to the type of file and damage. Some programs offer the option of recovering data from damaged SUNIFF files. The easiest way to restore the file is from a backup or by contacting Sun Microsystems, but this one can be expensive. Not all damage can be reversed.
The program can also signal the fact of encryption. The encrypted SUNIFF 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.
Some operating systems do not allow file operations in certain locations, eg in system directories or directly on the system drive. The problem is only writing to the file, not reading it. It is best to move SUNIFF to a different directory.
This problem usually affects more complex files. Some file types can only be opened in one program at a time. 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 SUNIFF file for a certain period of time. If this does not work either, restart the device.
