Tips to open FOR file

Can't open the FOR file? You are not the only one. Thousands of users face similar problems every day. Below you will find tips on how to open FOR files as well as a list of programs that support FOR files.

FOR file extension

File Name Fortran 77 Source Format
File Category Developer Files

The FOR file is supported on 3 operating systems. Depending on your operating system, you may need different software to handle the FOR files. Below is a summary of the number of programs that support and open the FOR file on each system platform.

What is FOR file?

The file with the extension FOR is the Developer Files file type. In addition to this file, the Developer Files category includes 1205 related files. Fortran 77 Source Format is supported by 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. It is recommended to use Apple Xcode to handle this file. This is a program created by Apple, Inc.. Alternatively, you can use 7 other programs. PSPad, Photran, Microsoft Visual Studio, Visual Fortran Compiler will apply when it is not possible to use Apple Xcode.

How to open FOR file?

An often recurring problem with Fortran 77 Source Format is that FOR is not associated with the correct program file. This is manifested by the fact that FOR 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 FOR 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 Apple Xcode

An often overlooked issue is to make sure that Apple Xcode is installed on the computer. The easiest method is to use the system search engine by entering the program name Apple Xcode in it. 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 FOR files.

Step 2. Create association of Apple Xcode with FOR files

If, despite the installed application, the FOR file does not start in the Apple Xcode application, you must create a file association. It is most convenient to call the context menu with the right mouse button and select 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. The "always use the selected program ..." field will set the Apple Xcode application as the default for handling the FOR file.

Step 3. Update Apple Xcode to the latest version

If, however, after binding Apple Xcode with Fortran 77 Source Format 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 Apple, Inc. website and install the latest version.

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

If the above steps do not help, you can assume that the file itself is not correct. The most common file problems are:

The affected file may be 0 KB or smaller than expected. This is most often caused by a problem while downloading the FOR file. The only repair option is to download the file again.
The most common cause here is computer viruses. A virus scan using an up-to-date antivirus program should fix the problem. Alternatively, you can use the scanners available online. The scan should cover the entire computer, not only the FOR file that we want to open. Sometimes virus-infected FOR files cannot be recovered, so make a backup in advance.
Older version of FOR file may not always be supported by the latest software version. 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. Depending on the type of file, it is necessary to repair it accordingly. Some programs offer the ability to automatically repair FOR file corruption. You can restore the file from a backup or use N/A help.
When reading, a message appears that the file was encrypted or corrupted. The encrypted FOR 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. While there is usually no problem reading such a file, it may not be possible to save it. If possible, you can try to move the FOR 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 FOR to close. Some anti-virus or backup software may occupy the FOR file for a certain period of time. If the problem persists, restart the machine.
