Retrieve Files in Folders over FTPS - Not able to download single file

Hi Team,

Using the "Retrieve Files in Folders over FTPS", i was able to download all files from folder when i specify the folder path.

But if i specify a single file along with it's path, then the file is downloading as <1 KB file and not able to download and open.

Please help me , on how to download single file using this plugin ?

Thanks in advance....
