Konqueror is a very good way to manage this too.
It permit direct edition and file modification on distant server where winscp need download and upload.
The advantage of a linux live system is that it can't be compromised by virus, spyware,rootkit or keylogger cause it use a read only filesystem (cd or dvd) and mount all partition in read only mode at startup, it's also a very good rescue tool for win crash

Sorry for my bad english...
