High Precision Folder Matching (HPFM) for faster open source scanning
Instead of matching every file individually, HPFM analyses the full structure of a scanned folder—file names, directory layout, extensions, and contents—to quickly determine which open source component it most likely represents.
Think of it like scanning a car: traditional scanning lists all the parts; HPFM tells you “this is a Peugeot 2008.”
Why it’s useful: – Speeds up scanning in high-volume environments – Reduces noise by focusing on the dominant component – Can improve the accuracy of follow-up scans by providing a “hint” – Helps detect altered or incomplete components
Available now in scanoss-py. Docs/GitHub: https://github.com/scanoss/scanoss.py CLI: scannos-py folder-hash <directory>
Would love to hear feedback, suggestions, or use cases this might help with.
The correct command is:
scannos-py folder-scan <directory>
folder-scan (fs) --> Scan the given directory using folder hashing
folder-hash (fh) --> Produce a folder hash for the given directory
