Game Library Portability Manager
A desktop app that helps players move, archive, and launch games across internal and external drives without guessing about performance or offline readiness. It addresses the strongest software-solvable pain in the discussion: storage pressure combined with a desire for portable ownership-like workflows.
これが重要な理由
You run out of fast storage long before you run out of games. When every major title demands a large install, you start juggling files across internal SSDs, external drives, and multiple launchers, with no confidence about what will still launch cleanly later. You also want more control over what you truly own locally versus what still depends on a platform check or a fresh download. The frustration is not only disk space; it is the constant uncertainty about performance, recoverability, and whether moving a game off your main drive will create a future headache.
- · PC gamers with large multi-launcher libraries, limited SSD space, and frequent use of external SSDs or backup drives.向けに構築。
- · 最も可能性の高い収益化モデル: Freemium desktop app with Pro subscription。

エビデンスの概要
AIがこのインサイトをどのように統合したか — 逐語的な引用はありません
Storage pressure and removable-drive workarounds appeared repeatedly across the discussion, with roughly a dozen mentions tied to large installs and external media use. Users also showed mixed confidence about whether external storage performs reliably, which strengthens the case for a tool that combines move management with compatibility guidance rather than simple file transfer.
