As far as I know, I think you are going to be out of luck there. Every major file transfer protocol that I know of requires read privileges to even list the file/directory when the storage heap/mount is queried.
There are some weird file storage protocols out there that can expose/parse a file/directory name but prevent it from being accessed but these protocol settings are usually made at the storage adapter level. This is based on my experiences - there maybe someone else that knows something a little easier to implement...

The user is accessing the server using guacamole via RDP and it is required to allow uploading of files, but to prevent downloading. I have tried to set the permissions on the drive-path but it didn't work, either it disables file transfer completely or it works in both directions. Maybe I have missed something here. Is it possible to implement this functionality using extensions? I couldn't find much documentation about creating extensions, only some basic examples for UI customization. What would be the correct approach for such functionality?
