Download Files without Listing Folder (sftp)

Will be creating Files like such

username: generic_user
home/fileA.zip
home/fileB.zip

Want to be able to give generic_user ability to download fileA.zip only - user should not be able to list all files in home_folder

1. Is this possible on any sftp server ? using Winscp as Client?
2. If yes is it possible in Chrome/Firefox to download ?
3. Is it possible in batch or command-line (winscp.com) ?

TY for your time.

WinSCP scripting is able to download a file from an SFTP server without having listing permissions to the directory. WinSCP GUI cannot do that.

Chrome/Firefox do not support SFTP.
