Press the button in the top-right of the main window and select
Scan Remote Folder….
Enter the URL into the Server Address field. It will
normally have a protocol, followed by a colon and two slashes, that looks
different depending on the protocol that you are using.
Click Connect to continue; you may be asked for more
details, like a password and username, before the scan will commence.
通过网络扫描可能比扫描本地文件系统速度慢些。
You can also select a recently used server instead of entering a new URL.
If you enter a URL which is not valid, you will not be able to press
Continue, but if the URL is valid, but incorrect, the connection
will fail without warnings.
