What is an AFB file?

AFB files mostly belong to Adobe Flash. AFB files are not a single, uniform format. They refer to several data types used in different sectors.

Bank statement files: In some cases, an AFB file is an account statement file. It stores banking records like transactions and balances. This file type is used by financial systems for record keeping.

Game animation files: Another AFB variant is used to hold animation data in games such as Arcaea. These files follow conventions similar to Adobe Flash animation and integrate with systems like CRI Middleware’s file system. For more details, visit the Arcaea website.

Backup and Adobe Flash Builder data files: Some AFB files act as backup files—like those in Sage 50 France environments—or serve as Adobe Flash Builder project data. These files often use UTF-16 (LE) encoding.

It is essential to identify the context of your AFB file before using or editing it. Use the appropriate software: banking applications for account statements, Adobe Flash tools or game editors for animations, and the correct backup utility for Sage 50 data.
Tip: Always back up your file before making any changes because its internal structure can be complex and varies with each use case.
FilExt.com note: Few people know that game animation AFB files may encapsulate multiple layers of frame data, requiring specialized tools to fully extract and edit their contents.

How to open AFB files

AFB file format:

Why is it important to know the file format? This is the only way to find out which program to use to open the file. Each file format has a unique extension and almost always a unique signature. For example, Microsoft Word documents have the extension .docx and the signature (usually the first 3 characters in this file) PK. Frequently, however, one file extension is used by different programs for different file formats, and one file format for different file extensions. When there is a problem with a file, the first step to solving it is to determine the file format. Our analysis of the AFB files produces the following result:

The AFB file extension is rather rarely used and covers different formats for different programs. But the following two file formats are common:

• 40% of all AFB files use the same file format, which can be identified by the letters "01" at the beginning. These files contain text and words, not binary data. The files are often between 480 bytes and 18 KB in size. The file type is very recent. The file name afb_tous_comptes_20180601_20180601.afb or BtFile.AFB is characteristic of these files. Files like these are about mvtbt, comptes and tous.
• 25% of all AFB files start with the magic bytes FILS, which are always the first bytes of this file format. These files are binary files, so they do not contain text, but only cryptic characters. The average file size is 1 MB with most files being between 57 KB and 4 MB in size. The files contain the following words: FILS, FILE and AFNC. A common filename is chu_count_border.afb. Files like these have the following tags: label, count, border, basic, yellowring and text.

All other AFB files (35%) have different formats, the following 5 formats can be found: AYFX Editor Bank, UTF-16 (LE) and JSON. The category is attack, rlvcf, flow, infantoon, action, tiamat, unknow, mitre, nerve or bomb. Just click the "Choose your .afb file to analyze" button on this page to find out what your AFB file is.
