How it works

01
Understand
labkit scans your device, SD card and existing files, and identifies every game against curation metadata. A truthful picture before anything moves.
02
Plan
Pick a curated 1G1R list, set your space budget, and get a plan you can actually read: what is kept, what is skipped, and why.
03
Execute
Every change runs as a dry-run first. You approve; labkit syncs. Nothing is deleted, moved or converted without your explicit sign-off.
