What is IRAF file?

The file with the extension IRAF is the Graphic Files file type. It was designed by NOAO. In addition to this file, the Graphic Files category includes 524 related files.

How to open IRAF file?

An often recurring problem with IRAF is that IRAF is not associated with the correct program file. Thus, when you open IRAF, the program selection wizard or some other program starts. How to solve such a problem?

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

In this case, you should first verify that the IRAF application is installed on the computer. This can be achieved by typing IRAF into the operating system search engine. If it is not, installation may solve the problem, as most applications create file associations during installation. Later in this article you will find a list of programs that can open IRAF files.

Programs to open IRAF file

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

Step 2. Create association of IRAF with IRAF files

If the application is or has been freshly installed, but the IRAF file still does not use the IRAF program, it means no association. The association can be created using the drop-down list available by right-clicking on the file and selecting Properties. 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 select the desired program. It may happen that in the next window there will be no appropriate program - however, this can be corrected with the "Browse" option where you should manually indicate the program location. Checking the "Always use the selected program ..." box will permanently associate the IRAF file with the IRAF program.

Step 3. Update IRAF to the latest version

The fault may also lie with the IRAF program, it is possible that IRAF requires a newer version of the program. Some applications allow you to update from the program level, and for others you need to download the installer from the NOAO page and install.

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

Of course, it may happen that despite the above steps, the file still does not work. This could be due to the file itself, the cleanest issues are:

The IRAF file may be unusually small compared to the original file. This is most often caused by a problem while downloading the IRAF file. Downloading the file again should fix the problem.
The operating system may be infected with a computer virus. Perform a virus scan using available and up-to-date anti-virus software. If this is not possible, you can use the online scanner. The scan should cover the entire computer, not only the IRAF file that we want to open. As a result of the scan, sometimes it is not possible to recover IRAF files, which are deleted if there is a backup of this file, then after restoring it, it must also be scanned.
A typical compatibility error - the program does not support the older version of the IRAF 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.
The file may be corrupted in a number of ways. The repair method must be adapted to the type of file and damage. Some programs offer the ability to automatically repair IRAF file corruption. The easiest way is to restore the file from a backup, if there is one, or contact NOAO
When reading, a message appears that the file was encrypted or corrupted. The encrypted IRAF 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 operating systems do not allow file operations in certain locations, eg in system directories or directly on the system drive. These directories are write-protected to them and it's very hard to fix this problem. Copying the IRAF file to another location will fix the problem.
This problem usually affects more complex files. In this case, the IRAF file is blocked by the first application to open it. Closing other programs should help. If the error persists after closing other programs, wait for a while. Antivirus programs or a backup being made may lock the file for a while without the user's knowledge. If this does not work either, restart the device.
