About ATR files
The .ATR file extension is heavily fragmented and serves entirely different purposes depending on the industry. Most commonly, it functions as an Atari 8-bit Disk Image used to store retro software. In academic and medical fields, it is an ECG Annotation File used to mark cardiac events in physiological recordings. It is also actively used as an ANSYS Engineering Simulation Result, an Allplan CAD Attribute File, and a FLIR Thermal Imaging Report.
Because these files serve completely different industries, opening them requires specialized software. Atari images open in emulators like Altirra or Atari800. Medical data requires the WFDB Software Package or BioSig. Thermal reports open in FLIR Tools.
The primary disadvantage of the .ATR format is this extreme fragmentation. Your operating system will not know how to open it by default, and double-clicking it usually results in an error. Furthermore, the proprietary variants (like ANSYS or Nemetschek Allplan) lock your data behind expensive commercial software licenses. Medical .ATR files are often binary or specialized text formats that cannot be easily graphed in standard spreadsheet software without tedious data wrangling.
To bypass these roadblocks, you must convert the file based on its underlying data type. For medical and physiological annotations, convert to CSV or TXT to seamlessly analyze the data in Excel or Python. For FLIR thermal reports, extract the contents to access the raw JPG images, or convert the entire report to PDF for easy sharing. For Atari disk images, convert to XFD format for broader emulator compatibility. Drag and drop your file here to instantly analyze its true format and convert it securely right in your browser.
Convert.Guru analyzes your ATR file, detects the exact format, and lets you read the text inside.
If you want to convert ATR file to PDF, ISO, IMG, DMG, VHD, VMDK, VDI, HDD, QCOW, QCOW2, RAW or VBOX, you can use WFDB Software or similar software from the "Disk Image or Medical Data" category. In the File menu, look for Save As… or Export….
To convert VFD, DMG, OVA, IMA, VBOX, ADF, PVS, VHD, OVF, ISO, DSK or IMG files to ATR, try WFDB Software or another comparable tool in the "Disk Image or Medical Data" category.
The ATR Converter Story
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our ATR converter.
