What is an AOF file?

AOF files mostly belong to Redis server.

Redis Append-Only File: AOF files are used by Redis to log every command that changes the database. This file helps the server rebuild the database after a restart. Its content is line based and can be viewed with a text editor, though it is best handled by Redis itself. See details at Redis official site.

Artlantis Object File: These files use XML to store 3D object information for rendering in Artlantis software. The XML structure holds scene data and object attributes. For more, visit Artlantis.

Qualcomm Log File (Adaptive Optimization File): Employed by Qualcomm QCAT, these files log event data used for troubleshooting and network investigations. They support TEMS Investigation. More info is available at Qualcomm.

FilExt.com note: Although the AOF extension is shared, each file’s content and purpose depend on the originating software. Always open and edit these files with the respective application to avoid misinterpretation of the data.

How to open an AOF file

You need a suitable software like Redis server to open an AOF 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 AOF file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a AOF file directly in the browser:. Just drag the file onto this browser window and drop it.

AOF file format:

If you can determine the file format, the associated program can also be determined. The file format can be determined based on the file extension and the signature (the first few characters of a file). However, different programs can use the same file extension, and file extensions can be assigned incorrectly. Knowledge is power - this also applies when dealing with unknown or faulty files. Our analysis of the AOF files produces the following result:

The AOF file extension is not found very often and includes different formats for the applicable programs. The file formats most commonly found in AOF files are:

• 35% of all AOF files are Artlantis Object File files, which are based on the XML file format. The Extensible Markup Language (XML) is a simple text-based format for representing structured information: documents, webpages, data, configuration, books, transactions, invoices, and much more. XML defines a set of rules for encoding documents in a format that is both human-readable and machine-readable. These files are text files, so they contain words and text. The files are on average 1 MB in size and range from 300 KB to 45 MB. This is an old file type which is rarely used today. The files contain the following words: <?xml version="1.0" encoding="UTF-8"?>, <Atl.File>, <Preview.Image><![, <?Atl library="4.1.0" file="5.0" min_version="2.0.0" safe_version="2.0.0"?> and <?Application name="Artlantis" version="Jun 7 2012"?>. Grass_10x10m_5sm.aof or Grass_5x5m_5sm.aof is a typical file name. Such AOF files store data about person-related data.
• 15% of all AOF files start with the magic bytes REDIS0009ú redis-ver, which are always the first bytes of this file format. The content consists of binary data as well as text and words. AOF files are between 150 bytes and 51 MB in size. The keywords REDIS0009, aof-preamble, ctime, redis-bits, redis-ver and used-mem are typical for these files. A common filename is appendonly.aof or postauth.aof.

The remaining 50% of all AOF files are files with no common format, the following 4 formats exist: SELECT and AOF. They are often associated with incr or export. Drag & drop your file here to see the file format and a preview of your AOF file!
