Extract text from ACF files
To convert your ACF file to another format, you need Valve Steam or other Settings software.
To convert other file formats to the "Game Data File" file type, you need software like Valve Steam or a similar tool.
The .ACF extension is most frequently associated with the Steam Application Manifest, a critical configuration file used by the Valve Steam client. These files, such as appmanifest_570.acf, store essential metadata about installed games, including the App ID, installation directory, update status, and current build ID. While they are plain text files formatted in Valve's proprietary KeyValues structure, they are not designed for user interaction. A common issue arises when moving game libraries between drives or restoring backups; if the .ACF file is missing or corrupt, Steam will fail to recognize installed game files, forcing a re-download. Users often need to convert or view these files as standard TXT or JSON to manually edit paths, debug library issues, or integrate game data into third-party launchers.
A secondary but significant use is the X-Plane Aircraft File used by Laminar Research X-Plane. This text-based format defines the physical properties and performance characteristics of simulated aircraft. Enthusiasts and modders often need to access this data to tweak flight models, requiring conversion to a more readable text format if they lack specialized editing tools.
Convert.Guru analyzes your ACF file, detects the exact format, and lets you read the text inside.
Users also converted TXT, XCF, AVIF, RTF, PDF, RAR, ZIP, ACSM, PSB, ACT, AMP, SCF and MCF files.
If you want to convert ACF file to SCF, MCF, EXE, ISO, BIN, CUE, PAK, WAD, PK3, PK4, BSP or MAP, you can use Valve Steam or similar software from the "Game Configuration & Manifest" category. In the File menu, look for Save As… or Export….
To convert MOD, BIN, CFG, SCX, DAT, MPQ, LOG, CUE, INI, EXE, SCM or ISO files to ACF, try Valve Steam or another comparable tool in the "Game Configuration & Manifest" category.
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 ACF converter.
