About the SFW format
SFW — Seattle Film Works
SFW is a proprietary image format used by Seattle Film Works (later PhotoWorks), a film processing service that offered digital images on floppy disks. These files are legacy digital scans from the 1990s when SFW was one of the first mass-market film digitization services.
Common uses
- Recovering Seattle Film Works digital photo scans
- Converting 1990s SFW disk photos to modern formats
- Legacy film scan archiving
- Historical family and event photo recovery
About the TXZ format
TXZ — XZ-compressed TAR Archive
TXZ (also .tar.xz) is a TAR archive compressed with the XZ algorithm, which is based on LZMA2. It provides the highest compression ratios of the common tar formats, making it the preferred choice for official Linux distribution packages (Arch, Fedora, Gentoo). The trade-off is slower compression speed versus gzip or bzip2.
Common uses
- Official Linux distribution package format (e.g., Arch Linux)
- Maximum compression of large software releases
- Distributing firmware and embedded system images
- Archiving large datasets for long-term storage
