     SFTPGo also supports virtual folders, a virtual folder can use any of the supported storage backends. So you can have, for example, an S3 user that exposes a GCS bucket (or part of it) on a specified path and an encrypted local filesystem on another one.
     Virtual folders can be private or shared among multiple users, for shared virtual folders you can define different quota limits for each user.
     SFTPGo allows to create HTTP/S links to externally share files and folders securely, by setting limits to the number of downloads/uploads, protecting the share with a password, limiting access by source IP address, setting an automatic expiration date.
