Extract text from SquashFS filesystems (SFS)
To convert SFS filesystems to another format, you need 7-Zip or other Compressed software.
To convert other file formats to the "Linux Filesystem Archive" file type, you need software like 7-Zip or a similar tool.
The .SFS file format most commonly represents a SquashFS compressed filesystem. Designed for Linux, these files store an entire read-only directory structure using block-level compression. They are heavily utilized in Live CDs, router firmware, and embedded devices. Alternatively, .SFS serves as a proprietary game save or archive format for popular titles like Starfield, Kerbal Space Program, and IL-2 Sturmovik.
For SquashFS files, Linux users rely on the squashfs-tools package (specifically unsquashfs) to extract data. On Windows systems, 7-Zip can reliably unpack many standard .SFS filesystem images. Game save and proprietary archive variants are strictly managed by their respective game engines or dedicated modding utilities.
The primary disadvantage of a SquashFS .SFS file is its lack of native support on consumer operating systems like Windows or macOS. Users cannot simply double-click the file to browse its contents; it must be explicitly mounted via command-line or extracted using third-party software. The game save variants pose a different challenge: they are proprietary, obfuscated binary files strictly locked to specific software engines. Attempting to force them open in standard text editors will result in unreadable characters.
Converting an .SFS file usually means extracting its contents rather than transcoding it. For SquashFS archives, the most practical targets are universal archives like ZIP or TAR, which guarantee cross-platform access. If you are handling an .SFS report file from Fast Reports, exporting to PDF is the standard path. Game saves, however, cannot be cleanly converted into standard documents without corrupting the save data.
Because an .SFS file can be a complex compressed filesystem, an encrypted game save, or a specialized database backup, standard online tools frequently fail to process them. Often, only the original game engine or specific Linux kernels can properly interpret the raw data.
Convert.Guru analyzes your SFS file, detects the exact format, and lets you read the text inside.
Users also converted MP3, ZIP, RAR and XZ files.
If you want to convert SFS file to MP3, WAV, AAC, FLAC, OGG, WMA, M4A, AIFF, OPUS, ALAC, APE or WV, you can use 7-Zip or similar software from the "Compressed Read-Only File System" category. In the File menu, look for Save As… or Export….
To convert MIDI, AAC, TTA, AU, WV, DTS, MID, FLAC, RA, MP3, PCM or WAV files to SFS, try 7-Zip or another comparable tool in the "Compressed Read-Only File System" 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 SFS converter.
