🎉 MkPFS 1.1.0 is released!

🤖 What's Changed

Some bug fixes related to compression, dependencies upgrades and restored the PS4/PS5 selector from th GUI. Including:

• Add PS4 and PS5 version selectors to GUI (#136) @RenanGBarreto, @Phoenixx1202
• Prevent PS5-unsafe automatic ISA-L compression (#135) @RenanGBarreto, @Creazawolf
• Update GUI metadata layout and batch preview (#124) @Phoenixx1202
• Multiple dependency updates

🚀 Quick Start

# Install/Update using pip
python -m pip install -U "mkpfs"

# Creating Images: Option 1: .exfat -> .ffpfsc (Works with ShadowMountPlus)  (Maximum compatibility)
python -m mkpfs pack file './BREW1234.exfat' './BREW1234.ffpfsc'

# Creating Images: Option 2: .ffpkg -> .ffpfsc (Works with ShadowMountPlus) 
python -m mkpfs pack file './BREW1234.ffpkg' './BREW1234.ffpfsc'

# Creating Images: Option 3: Game folder -> .ffpfsc in one pass (default: exFAT-wrapped, no temp file)
python -m mkpfs pack folder './BREW1234-app' './BREW1234.ffpfsc'

# Creating Images: Option 4: Game folder packed directly as PFS (advanced single-pass)
python -m mkpfs pack folder --raw './BREW1234-app/' './BREW1234.ffpfs'

# Creating Images: Option 5: Game folder wrapped twice into PFS (advanced two-pass)
python -m mkpfs pack folder --raw --no-compress --no-adjust-output-file-extension './BREW1234-app' './pfs_image.dat'
python -m mkpfs pack file './pfs_image.dat' './BREW1234.ffpfsc'
rm './pfs_image.dat'

# Extracting Existing Images (Reverse operation; --deep lists/extracts inside a wrapped exFAT)
python -m mkpfs unpack  --deep './BREW1234.ffpfsc' './BREW1234-extracted/'

⚠️ Limitations and Known Issues

• exfat->ffpfsc is the most stable format for compressed game backups. pack folder produces this layout by
  default: it wraps the folder in an exFAT image and compresses that into the .ffpfsc in a single pass, with no
  temporary .exfat on disk.
• pack folder --raw packs the folder directly into a PFS image without the exFAT wrapper. When file compression is
  enabled, the image is created and verification passes, but the console reads the files incorrectly due to technical
  limitations, so this advanced option provides no practical benefit for game backups. Prefer the default wrapped
  layout.
• With the default --block-size 65536, very small files can cause significant block-alignment waste, which may make
  the resulting image larger than the source in corner cases.
  • For small-file-heavy folders, prefer the two-pass strategy (raw-folder -> .dat -> .ffpfsc) or try a smaller
    block size such as --block-size 16384 or --block-size 32768.
• Antivirus scanning can reduce conversion speed, especially during the write phase or when processing many loose
  files. If you trust this software in your environment and need higher throughput, temporarily disabling real-time
  scanning can help. If you are unsure, keep antivirus enabled and expect slower conversions.
