If you work with files stored on a home server, NAS, or office file share, a network drive can make access much more convenient. The problem is that network locations depend on your connection. If Wi-Fi drops, the VPN disconnects, or you take your laptop away from the office, those files may become unavailable.

That’s where Offline Files comes in. In supported Windows editions, you can map a network drive and cache its contents locally so your files remain available even when the network share is temporarily unreachable. When you reconnect, Windows syncs your changes back to the server.

This guide walks through the full setup in Windows 10 and Windows 11, including how to map the drive, enable offline access, and avoid common pitfalls.
