Thanks Bhaskar,
Seems like My issue is not related :(colon) as I am able to authenticate successfully for folders.
Authentication is completed successfully when I am giving SFTP://xxxx.xxx.xxx:22/F:/Folder1/Folder2/Folder3/ as my source system is having F:/Folder1/Folder2/Folder3.
But if I put any file inside folder , event not able to find any of file.
If I give a shared folder how can we give a SFTP url for authentication?
