What is an ATP file?

ATP files mostly belong to TurningPoint. ATP files are data containers used by various software systems. They do not have a single standard design but instead come in different internal formats that match their use.
When you see an ATP file, it is likely one of the following types:

• Polling Data Files: These files store poll session or audience response data. Some use UTF-16 (LE) or XML encoding. For example, files created by PresenterMedia for TurningPoint sessions or by WebEx Meetings (see PresenterMedia and WebEx) follow this pattern.
• Game Modification and Animation Packs: In some cases, an ATP file is a ZIP archive containing an Animation Text Pack format. This is common in mods for games like Friday Night Funkin', where the file supports the Psych Engine.
• Audio Track Files: Some ATP files are simply MP3 audio tracks, used as standalone media.
• Player and Sports Data Files: Other instances include files holding player statistics for sports games, such as football or tennis data from companies like Pro Evolution Soccer or ATP Tour Tennis Data.
• Automation and Testing Files: A few ATP files serve as test automation or preset files (sometimes encoded in XML), used in specific applications like those from Prima Test Automation or Ableton Live.

Each file’s function depends on the originating software. The internal structure—whether it is ZIP, XML, or MP3—provides clues on how to open and view it.
FilExt.com notes: If you are trying to open an ATP file, check the file header or encoding to decide which application is needed. For poll and audience response files, using the original vendor software (like TurningPoint from PresenterMedia or WebEx Meetings) is the best approach. For game mods, instructions are often available on community sites such as GameBanana.

How to open an ATP file

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

ATP file format:

Each file has a definite file format, that is, how the stored data is arranged in 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. 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 evaluation of the ATP files is as follows:

The ATP extension is very commonly found and mainly uses a defined ATP format. The following file formats are most commonly found in ATP files:

• 70% of all ATP files are using the well-known XML file format to store the data. 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 are binary files, so they do not contain words or text. The files are often between 650 bytes and 6 KB in size. The file type was created recently. The keywords <?xml version="1.0" encoding="UTF-16"?>, NOANSWER, named and <POLL TYPE="anonymous" SHOWTIMER="yes" ALARM="5:0" NOANSWE are typical for these files. Examples of file names are Poll.atp or Poll1.atp. These files are attributed to questions, question, sondaggio, polling, session, survey, results and umfrage.
• 10% of all ATP files belong to ATRAC encoded audio. The files are using the common file format MP3. MP3 is an audio file format that uses a compression algorithm to reduce the overall file size of songs, sounds or pieces of music. These files contain neither text nor words, but only data. ATP files are between 1 MB and 3 MB in size. The keywords vTIT2, TPE1 and TALB are typical for these files. An example of a file name is TRK0000A.ATP or TRK0000B.ATP.

The remaining 20% of all ATP files are different files with different signatures, often e.g. ZIP, pta and Definition. Files like these are sometimes linked to pack, lesson, tricky, quiz, madnesscombat, feedback, sondeo, slide or webex.
