AFS	File extension: AFS

What is an AFS file?

AFS files mostly belong to STAAD Foundation by Bentley. An AFS file is a building foundation design project created with STAAD Foundation design and analysis program. The file contains 2D/3D components of a building's foundation and reports on the structural soundness of the design. Another type of AFS file contains a text-encoded specification of an active filter circuit created with AktivFilter circuit design software. Type Manager, a program that adds PostScript font support to older operating systems, saves a font set in an AFS file. FreeBSD operating system saves some data in a file with AFS filename extension. Dreamcast video games use soundtracks saved in AFS files.

How can I open an AFS file?

You need a suitable software like STAAD Foundation to open an AFS file. Without proper software you will receive a Windows message "How do you want to open this file?" or "Windows cannot open this file" or a similar Mac/iPhone/Android alert. If you cannot open your AFS file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a AFS file directly in the browser:. Just drag the file onto this browser window and drop it.

AFS format details:

The file format, which is the arrangement and type of data in a file, determines which program can open the file. The file format can be deduced from the file extension and the signature. If the file extension or signature does not match the file format, errors will occur when opening or editing the file. Knowledge is power - this also applies when dealing with unknown or faulty files. Below you will find our evaluation of the AFS files:

You will often come across the AFS file type. This is primarily used by a single program. But the following two file formats are common:

90% of all AFS files belong to AFS game data archive. They consist of unreadable binary data. The files are often between 1 MB and 700 MB in size. The file type was primarily used more than 20 years ago. Some examples of file names are bgm.afs. Such AFS files store data about voice, sound, text, data, demo, event, pack and movie.
2% of all AFS files are using the well-known JetDB file format to store the data. The JetDB is a database format often used by Microsoft Access and Visual Basic programs. JET is short for Joint Engine Technology. The contents of these files cannot be read by a human; only a computer program can interpret the data. Most of these files are 340 KB to 1 MB in size. Several words can almost always be found in the files, e.g. Standard.

The remaining 8% of all AFS files are files with no common format. Sometimes used for logos, entrance or battle. You can get all the details of your AFS file by dragging it onto this page or by clicking the button "Choose your .afs file to analyze" above.

How to solve problems with AFS files

Associate the AFS file extension with the correct application.
Update your software that should actually open building foundation projects. Because only the current version supports the latest AFS file format. Search, therefore, e.g. on the Bentley manufacturer website after an available STAAD Foundation update.
To make sure that your AFS file is not corrupted or virus-infected, get the file again and scan it with Google's virustotal.com.
