Jephe Wu -

1. Perfect way - map sftp server as Windows drive letter

expandrive - (30days trail)
webdrive -  (20 days trial)

Directnet drive - (free for home user only)  --it hung my Windows Vista Home Basic laptop

2. second option - ftp and webdav
Windows builtin functionality - map network drive for ftp server (lack of drive letter functionality)
note: choose tools/map network drive/signup online storage or connect to a network server/choose another network location, specify the address of a web site, network location or ftp site
