How Can I Permanently Share Files or Folders with Other Users?

You can use OBS Browser+ to share files or folders with other users through URLs. These URLs are valid for only a certain period. Once they expire, files or folders will not be accessed. If you want to share a file permanently, configure this file to be accessible from anonymous users, so anonymous users can access the file through the URL you shared. To share a folder permanently, configure a bucket policy that makes the objects prefixed with a certain folder readable for the public, so anonymous users can access all objects under that folder.

For details about how to configure a bucket policy and how to obtain an object URL, see Bucket Policy and How Do I Obtain the Access Path to an Object? respectively.
