All about ATR Files

The ATR file type is primarily associated with Xformer.

ATR	File extension: ATR
	File type:	disk image

What is an ATR file?

ATR files mostly belong to Xformer by Xformer Developers. An ATR file contains a single/double density disk image of an Atari system. A disk image contains the file system, drivers, and resources required to set up an Atari environment. Atari system emulators such as Atari800Win and Xformer can mount and install an ATR disk image. Another type of ATR file is a half-hour, two-channel electrocardiogram (ECG) recording saved as part of MIT-BIH Arrhythmia database. MATLAB can visualize such ECG recordings. A different ATR file contains the attributes report of a printed circuit board created with OrCAD PCB Designer.

How to open ATR files

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

ATR file extension format:

A file format defines how the data in the file is structured. Often, the file format can be deduced from the file extension or the initial bytes (called the signature). However, different programs can use the same file extension, and file extensions can be assigned incorrectly. So you need a detailed analysis of a file to find out the format and the associated program. In the following you will find our evaluation of the ATR files:

The ATR file type is a very commonly used file extension and covers a large number of different file formats. The two most common formats are as follows:

15% of all ATR files start with the bytes 00 58, which are crucial for this file format. The content consists of binary data as well as text and words. ATR files are between 80 bytes and 1 KB in size. It is a modern file type. Certain words are almost always found in the files, such as ## time resolution: 500. rec_1.atr or rec_2.atr is a typical file name. Files like these have the following tags: infant, resistance and bike.
15% of all ATR files start with the bytes 96 02, which are crucial for this file format. These files are binary files, so they do not contain text, but only cryptic characters. ATR files are between 13 KB and 130 KB in size. Files like these have the following tags: atari, seban, brothers, avalon, basic and disk, and often contain personal information.

The remaining 70% of all ATR files are files with no common format, often e.g. ZIP, Relax, NODE and AFIB. These files sometimes refer to subject, tempeda, fixed, exdm, animation, report, clust, probe, high or rank. If you want to find out what your ATR file contains, drag and drop it onto this page.

How to solve problems with ATR files

Associate the ATR file extension with the correct application.
Update your software that should actually open disk images. Because only the current version supports the latest ATR file format. Search, therefore, e.g. on the Xformer Developers manufacturer website after an available Xformer update.
To make sure that your ATR file is not corrupted or virus-infected, get the file again and scan it with Google's virustotal.com.
