TAT file format:

The file format, which is the arrangement and type of data in a file, determines which program can open the file. Often, the file format can be deduced from the file extension or the initial bytes (called the signature). If the file extension does not match the file format, double-clicking on the file will cause an error upon opening. So a detailed analysis of a file is vital in order to determine the format and the associated program. Our evaluation of the TAT files is as follows:

The TAT file extension is not common and is used by many programs, each with its own file format. The file formats most commonly found in TAT files are:

• 15% of all TAT files start with the bytes AVAILITY TA1 INTERCHANGE ACKNOWLEDGEMENT, which are crucial for this file format. These files are plain text, which means they can be viewed with any text editor such as Windows Editor, Nano for Linux, and TextEdit for macOS. The average file size is 970 bytes with most files being between 940 bytes and 980 bytes in size. The following keywords are characteristic: AVAILITY TA1 INTERCHANGE ACKNOWLEDGEMENT, Customer ID, Date Received, Time Recei and File Status: REJECTED.
• 8% of all TAT files store the data in 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. The content consists of readable text data, which can be read using a text editor. TAT files can be up to 8 KB in size, but are often around 1 KB - 5 KB. Several words can almost always be found in the files, e.g. <?xml version="1.0" encoding="utf-8" standalone="yes"?>, <filters>, NET version, TextAnalysisTool, excluding, showOnlyFilteredLines, <filter enabled="y", True and description.

All other TAT files (77%) have no consistent format, frequently e.g. RTF and version. These files are often connected to training, avantes or config. Just click the "Choose your .tat file to analyze" button on this page to find out what your TAT file is.
