Pier mounts WebDAV (Nextcloud, ownCloud, Synology, QNAP), SFTP and NFSv3 storage as a real Windows drive with its own letter, so any program can open files from a NAS or cloud server as if they were local.

• Files are read in blocks into a local cache, so large files open quickly
• Interrupted transfers resume, and the drive reconnects on its own after a connection drop
• Keeps working offline from the cache
• SFTP needs nothing on the server beyond SSH

Free for up to 5 drives; Pro is USD 19 per year. Windows 10/11 64-bit.
