Free App Stow Verifies Memory Card Backups Before Wiping

digital · 2026-07-23

Luke Lv, founder of UK-based video production studio lümira, has released Stow, a free app that ensures memory cards are fully backed up before wiping. Stow copies a card's contents to two drives simultaneously, then verifies every byte against the original without writing to the card. It addresses the lack of data verification in macOS and Windows native file systems, which can allow corrupt files to go undetected until after reformatting. The app is free, requires no account, and has no in-app purchases. It is not yet certified by Apple or Microsoft, requiring users to follow a security workaround to install. Lv plans to obtain certification next. Stow is available now for download.
