Extract text from Affix and forensics files (AFF)
To convert AFF Files to another format, you need Hunspell or other Data software.
To convert other file formats to the "Dictionary & Disk Image" file type, you need software like Hunspell or a similar tool.
The .AFF file extension primarily serves two highly technical purposes: plain-text Hunspell Affix files used for spell-checking dictionaries, and Advanced Forensics Format disk images used in digital investigations. Hunspell .AFF files define morphological prefix and suffix rules and are always paired with a corresponding DIC dictionary file. Meanwhile, AFF disk images store raw, bit-for-bit physical disk data alongside investigative metadata, originally developed by Simson Garfinkel and Basis Technology.
Both formats present distinct, real-world challenges. Hunspell affix files are technically plain text, but they rely on extremely dense, custom syntax that is difficult to read or manipulate without dedicated linguistic developer tools. Forensic .AFF disk images suffer from limited native operating system support; you cannot mount them directly using Windows Explorer or macOS Disk Utility. They typically require specialized, often expensive e-discovery suites to open and analyze.
To bypass these workflow limitations, format conversion is often the most pragmatic solution. For dictionary editing or linguistic research, convert the .AFF text data to standard TXT or CSV to cleanly parse the rules in a standard spreadsheet. For forensic files, convert the proprietary image to a universally supported raw DD, ISO, or IMG format to ensure maximum compatibility across standard mounting and analysis software.

Convert.Guru analyzes your AFF file, detects the exact format, and lets you read the text inside.
Users also converted AAF, SLT, VPD and PMX files.
If you want to convert AFF file to ISO, IMG, DMG, VHD, VMDK, VDI, HDD, QCOW, QCOW2, RAW, VBOX or OVA, you can use Hunspell or similar software from the "Spell Check & Forensic Images" 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 AFF, try Hunspell or another comparable tool in the "Spell Check & Forensic Images" 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 AFF converter.
