What is an AA file

AA files mostly belong to Audible. If you encounter a file with the AA extension, it may belong to one of two distinct groups:
Compressed Archive:

• Function: It can be a split part of a larger archive that uses the GZIP compression method.
• Details: These files are often assembled using tools like 7-Zip when an archive is divided into segments.

Audible Audiobook:

• Function: It may store audio content for an audiobook, a format provided by Audible.
• Details: These files are usually DRM-protected and are meant to be played on platforms such as Audible.

FilExt.com tip: Because the same extension is used for different file types, check the file’s origin and its size or properties to decide the proper application for opening it.

How to open AA files

You need a suitable software like Audible to open an AA 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 AA file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a AA file directly in the browser:.

AA file format:

If you can determine the file format, the associated program can also be determined. The file format can be deduced from the file extension and the signature. However, different programs can use the same file extension. Furthermore, a file extension can be renamed incorrectly and double-clicking on it will then display an error when it is opened. When there is a problem with a file, the first step to solving it is to determine the file format. Our examination of the AA files comes to the following conclusion:

The AA file extension is rather rarely used and covers a large number of different file formats. However, the following two file formats are common:

• 7% of all AA files store the data in the GZIP file format. Gzip is a compressed archive file format. Gzip (GNU zip) is only capable of compressing a single file. These files contain neither text nor words, but only data. The files are 820 KB to 99 MB in size, with a median of 70 MB. An example of a file name is 20180601.tar.gz.aa. These files are attributed to ptcl and ntfs.
• 6% of all AA files use the ZIP format, i.e. an AA file contains several compressed files. An AA file can contain up to 25 files (mostly 1 - 16). If you'd like to see the images and files included, just rename the file extension to .zip and double-click. AA files are between 11 KB and 4 MB in size.

All other AA files (87%) have no uniform format, the following 7 formats can be found: Audible Audio, BZh and pro. Often described as unabridged, seetothepee, ringworld, wtar, expectations, izebfxoid, complete, series or bleak.
