What is RAS file?

The file in the RAS format belongs to the Raster Image Files category. It was designed by Sun Microsystems. Additionally, the Raster Image Files category contains 522 of other files. Sun Raster Graphic is most often found on 3 operating systems. 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 NeoOffice. This was created by Planamesa Inc.. There are also 10 alternative programs to handle the RAS file. You can use ACDSee, PaintShop Pro, Canvas, XnView in case NeoOffice cannot be used.

How to open RAS file?

An often recurring problem with Sun Raster Graphic is that RAS is not associated with the correct program file. This causes the file RAS to open by system applications not designed for this purpose, or to display a message that there is no associated program. This problem can be easily remedied.

The first thing you should do is just "doubleclick" on the RAS 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 NeoOffice

An often overlooked issue is to make sure that NeoOffice is installed on the computer. This can be achieved by typing NeoOffice into the operating system search engine. In the absence of an appropriate program, its installation in the vast majority of cases will fix the problem. Later in this article you will find a list of programs that can open RAS files.

Step 2. Create association of NeoOffice with RAS files

If, despite the installed application, the RAS file does not start in the NeoOffice application, you must create a file association. This option is available from the level of Properties of a specific file available in the context menu. The window will show, among other things, the type of the file and the information by which the program is used to launch the file. Using the "Change" button we can set the program to handle this type. The program should be visible in the window, otherwise it should be selected manually using the "Browse" button and the program installation directory should be indicated. However, it is important to check the "Always use the selected program ..." box, this will allow you to permanently associate the RAS file with the NeoOffice application.

Step 3. Update NeoOffice to the latest version

If, despite the association of the NeoOffice program with the Sun Raster Graphic file, the file still does not open, check the program version and possibly update it to the newest version. Some applications allow you to update from the program level, and for others you need to download the installer from the Planamesa Inc. page and install.

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

If the above steps do not help, you can assume that the file itself is not correct. This could be due to the file itself, the cleanest issues are:

The affected file may be 0 KB or smaller than expected. This is most often caused by a problem while downloading the RAS file. The file should be downloaded again, making sure that the process has finished correctly.
The operating system may be infected with a computer virus. Perform a virus scan using available and up-to-date anti-virus software. Some antivirus vendors also provide free online scanners. The scan should cover the entire computer, not only the RAS file that we want to open. Sometimes virus-infected RAS files cannot be recovered, so make a backup in advance.
This can happen especially when the program is dynamically developed and the structure of the RAS files changes over time. These problems are known and are often very easy to fix using the software developers's website.
There can be many reasons for this. Repairing is very dependent on the file type. Sometimes the program itself has options to repair the most popular RAS file corruption. The easiest way is to restore the file from a backup, if there is one, or contact Sun Microsystems
The program can also signal the fact of encryption. The encrypted RAS 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. While there is usually no problem reading such a file, it may not be possible to save it. It is best to move RAS to a different directory.
This problem usually affects more complex files. In this case, the RAS file is blocked by the first application to open it. Closing other programs should help. Sometimes it is necessary to wait a while before referencing the RAS file again. Some anti-virus or backup software may occupy the RAS file for a certain period of time. If this does not work either, restart the device.
