About OOK files

The .OOK file extension is an Arachne Batch Script used primarily by the Arachne DOS-based graphical web browser. It operates as a local script file that executes commands to open external DOS programs directly from the browser environment.

Originally developed by Michal Polák, Arachne was popular in the late 1990s for bringing a graphical internet experience to MS-DOS systems. The primary disadvantage of the .OOK format today is its severe obsolescence. Modern operating systems like Windows 11, macOS, or Linux do not natively recognize this extension. Double-clicking the file will usually trigger a frustrating 'unknown application' error, creating an immediate roadblock for users who simply need to view the code inside an old software archive.

Because an .OOK file is structurally identical to a standard BAT file, it contains unformatted plain text. We recommend converting .OOK files to standard TXT or PDF to ensure the script's code is easily readable and securely archived across modern hardware. Converting to BAT is also ideal if you intend to run the script in a DOS emulator. No actual data or logic is lost during these text-based conversions.

Standard online converters often fail to process .OOK files because the format is exceptionally rare, effectively abandoned, and lacks a standard MIME type. Emphasizing its obscure nature, usually, only the original legacy software can natively trigger it.

Convert.Guru analyzes your OOK file, detects the exact format, and lets you read the text inside.
