WS_FTP Server Web Transfer Module runs as a web application under Internet Information Services (IIS). This web application needs access to the file system on your FTP host or hosts.
Use these settings to specify a Windows user account that the Web Transfer Module uses to access folders on the WS_FTP Server host. This includes local system folders and network folders specified with a UNC name.
This Web Transfer account applies to all WS_FTP Server hosts, but it is applied differently depending on the host settings and the user database configured for that host.
You can check the settings for user database, top directory, and impersonation in the Host Details page for each WS_FTP Server host.
You can edit the Web Transfer Module Web.config file to change settings such as the maximum file size for transfers, and maximum number of files that can be transferred. See Web.config settings.
