This $30 app is the best purchase I've made for my Steam Deck

Transferring files between a Steam Deck (running Linux/EXT4) and a Windows PC is awkward by default. The Paragon Linux File Systems for Windows app ($30) solves this by making EXT4-formatted micro SD cards appear natively in Windows File Explorer, with no extra steps needed when reinserting the card into the Steam Deck. The post also covers free alternatives: using a USB-C hub to work directly on the Steam Deck, formatting the drive as NTFS and using PowerShell scripts, or using a KVM switch with a USB-C monitor for the most seamless (but most expensive) setup.
