What is RAST file?

The file in the RAST format belongs to the Graphic Files category. In addition to this file, the Graphic Files category includes 524 related files. Sun Raster Bitmap Image is supported by 1 operating systems. The file will work on Windows systems, unfortunately not on others. The XnView application is recommended to open the file. It was released by Pierre-Emmanuel Gougelet. This file type can also be opened by 2 other programs. ACDSee Photo Manager, PMView Pro will apply when it is not possible to use XnView.

How to open RAST file?

The main problem with Sun Raster Bitmap Image is that the RAST file is incorrectly associated with programs. Thus, when you open RAST, 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 RAST 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

The first step is to check if the computer has the XnView program installed. To do this, enter the name XnView into the system search engine. In the absence of an appropriate program, its installation in the vast majority of cases will fix the problem. Below you will find a list of applications that support RAST files.

Programs to open RAST file

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

Step 2. Create association of XnView with RAST files

However, it may happen that the application itself does not cause the RAST file to open in the XnView application, but you can set it manually. It is most convenient to call the context menu with the right mouse button and select Properties. The displayed window will contain information about the program that supports this type of file. 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. However, it is important to check the "Always use the selected program ..." box, this will allow you to permanently associate the RAST file with the XnView application.

Step 3. Update XnView to the latest version

If, however, after binding XnView with Sun Raster Bitmap Image there were still problems, you should update the program to the latest version. This can be done using the application (if it provides such options) or from the Pierre-Emmanuel Gougelet website and install the latest version.

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

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

The RAST file may be unusually small compared to the original file. This suggests truncating the RAST file contents when downloading or copying. The only repair option is to download the file again.
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 RAST file. As a result of the scan, sometimes it is not possible to recover RAST files, which are deleted if there is a backup of this file, then after restoring it, it must also be scanned.
This can happen especially when the program is dynamically developed and the structure of the RAST files changes over time. 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. Depending on the type of file, it is necessary to repair it accordingly. Some programs offer the option of recovering data from damaged RAST files. The easiest way to restore the file is from a backup or by contacting N/A, 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 RAST 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 of the system directories are excluded from modification. These directories are write-protected to them and it's very hard to fix this problem. It is best to move RAST to a different directory.
This can happen on a file that does not support multiple access. In this case, the RAST file is blocked by the first application to open it. Running programs (including those in the background) should be verified. Sometimes it is necessary to wait a while before referencing the RAST file again. Antivirus programs or a backup being made may lock the file for a while without the user's knowledge. If the problem persists, restart the machine.
