What is a TAS file?

TAS files mostly belong to TAS Editor. The TAS file extension is used in several different areas. The most common use is for game recordings in tool-assisted speedruns. In this role, the file is created by the TAS Editor and stores game save state information, often compressed with zlib. This type of file works with software like BizHawk to replay highly accurate game inputs.
Other uses include:

Trading Activity Statement: Files that contain trading data or telemetry attributes, used in financial systems.

Western Union Transfer: Files that serve as advice or transfer documents processed by Western Union TAS Processor. For more details, visit Western Union.

Compressed Archives: Some TAS files are archives. They may use internal formats like 7z or ZIP and can store items such as compressed 3D models (as seen with TAS-C) or tape archive collections, supported by software like WinRAR. See Graitec or WinRAR for more information.

Automation Scripts: Other TAS files are used for industrial and database automation. Examples include TwinCAT Automation Sequence files and Toad Automation Script files (which are often XML-based). More details are available at TwinCAT and ToadWorld.

FilExt.com tip: This varied usage means that the internal structure may differ (using methods like zlib, 7z, ZIP, or XML) and it is best to use the proper application to view or edit these files.

TAS file format:

To view or edit TAS files you need to know the file format, because it determines how the data in this file is stored. The first characters in a file identify the file format, for example, HTML files start with the bytes <html>. File extension, signature and file format must match; otherwise errors will occur when the file is opened. When there is a problem with a file, the first step to solving it is to determine the file format. Below is our analysis of the TAS files:

TAS is not that commonly used as a file extension. This file type includes different formats for the applicable programs. The file formats most commonly found in TAS files are:

20% of all TAS files save the data in zlib file format. Zlib is a compressed archive file format that supports several different data compression algorithms. zlib is also a crucial component of many software platforms, including Linux, macOS, and iOS. The contents of these files cannot be read by a human; only a computer program can interpret the data. The files are 8 KB to 25 KB in size, with a median of 23 KB. A common filename is 1.tas.
15% of all TAS files use the same file format, which have the signature 010000. The content consists of readable text data, which can be read using a text editor. Most of these files are 1 KB to 760 KB in size.

The remaining 65% of all TAS files are files with no common format, often, for example, XML, 7z and WESTERN. These files are often connected to advice. You can get all the details of your TAS file by dragging it onto this page or by clicking the button "Choose your .tas file to analyze" above.
