What is a .F file?
The file extension .F represents a Fortran Source Code file. This type of file is associated with programming in Fortran, a language often used for numerical and scientific computing. The .F file contains source code written in Fortran, which can be compiled to create an executable program.
The description mentions that this file is a Unix file archive compressed with the "freeze" file compression program. This means that the file, in addition to containing Fortran source code, has been compressed using a specific utility called "freeze." The freeze program is part of a set of tools known as freeze/melt/fcat, which are used for compressing and decompressing files on Unix-based systems.
However, it's important to note that the use of the freeze program has largely been replaced by more modern compression tools, specifically the GNU zip suite. This suite includes programs like gzip, gunzip, and zcat, which are widely used today for file compression and decompression.
To open a .F file that has been compressed with freeze, you can use the original freeze program if you have access to it. Alternatively, a program called ZipZag can also handle these files. ZipZag is a file archiver that supports a variety of file formats, including those compressed with freeze. By using ZipZag or similar software, you can decompress and access the contents of the .F file.
Verification
Our goal is to help people find the most up-to-date information about file extensions for Windows, Mac, Linux, Android and iOS. We researched over 10,000 file extensions and their respective programs that open those files. If you want to suggest edits or updates about .F file formats, example files, or programs that are compatible. Please contact us.
