What is F90 file?

The file with the extension F90 is the Developer Files file type. Developer Files consists of 1205 similar files. Fortran 90 Source Code Format is supported by 3 operating systems. The file will work on Linux, Mac OS, Windows systems, unfortunately not on others. There are also 8 alternative programs to handle the F90 file. PSPad, Intel Composer XE, Microsoft Visual Studio, Fortran Compiler will apply when it is not possible to use Pro Fortran.

How to open F90 file?

An often recurring problem with Fortran 90 Source Code Format is that F90 is not associated with the correct program file. This is manifested by the fact that F90 files open in unusual applications or do not have an assigned program. How to solve such a problem?

The first thing you should do is just "doubleclick" on the F90 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 Pro Fortran

An often overlooked issue is to make sure that Pro Fortran is installed on the computer. The easiest method is to use the system search engine by entering the program name Pro Fortran in it. If we do not have this program, it is worth installing it, as it will help you automatically associate the file F90 with Pro Fortran. Below is a list of programs that support the file F90.

Step 2. Create association of Pro Fortran with F90 files

If, despite the installed application, the F90 file does not start in the Pro Fortran application, you must create a file 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. Changes can be made using the "Change" button. 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. However, it is important to check the "Always use the selected program ..." box, this will allow you to permanently associate the F90 file with the Pro Fortran application.

Step 3. Update Pro Fortran to the latest version

The fault may also lie with the Pro Fortran program, it is possible that Fortran 90 Source Code Format requires a newer version of the program.

Step 4. Check for the following problems with the F90 file

The problem may also be with the file itself if the above steps don't work. File problems can be divided into the following:

The affected file may be 0 KB or smaller than expected. This is most often caused by a problem while downloading the F90 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. Some antivirus vendors also provide free online scanners. The scan should cover the entire computer, not only the F90 file that we want to open. As a result of the scan, sometimes it is not possible to recover F90 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 F90 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 option of recovering data from damaged F90 files.
The program can also signal the fact of encryption. The encrypted file F90 except for the special designation, works normally, but only on the device where it was encrypted, before transferring it to another machine, decryption is required.
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. If possible, you can try to move the F90 file to another location.
This problem usually affects 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 you have to wait for the session to the file F90 to close. Some anti-virus or backup software may occupy the F90 file for a certain period of time. If this does not work either, restart the device.
