You can use a network share anywhere that you specify a physical folder on the server. To do this, you must enter the UNC path to the shared folder. You must also specify an Impersonation account that allows the WS_FTP Server to access the UNC path. The Impersonation Settings are configured on the same page (Host Details page) as the Top folder.
If using Microsoft IIS, you must also give permissions to the shared folder to the Windows user account under which your web server's WSFTPSVR
folder is running. If that user cannot access the shared folder through the Windows explorer, you cannot access the folder via the WS_FTP Server Manager.
