hema,
The path you need to specify will depend on what the FTP server considers to be the home directory of the user who opens the connection.
I would suggest determining the correct path by FTPing to your server from the command line first. Under Windows, just fire up a command prompt and type "ftp [hostname]", then log in with the username and password you are using. Once you're logged in, you can type "pwd" to find out what directory is considered home for your username. You can also use "dir" to list the directory contents and "cd" to change into a subdirectory. Use those commands to navigate to where you expect your file to be, then use "pwd" again to get the path. If you append the filename to the end of this path, it should form a string that you can use with the LabVIEW FTP VI.
On an FTP server, use the forward slash in your paths, and the leading forward slash indicates root (not \\).
