SAP SFTP Adapter

HI FRIENDS,

I need your help in two points -

1 -- Is there a document on sdn which covers the detailed information on SAP SFTP adapter? I found few links online but they are only covering few features. None of them talks about any limitation on the adapter.

2-- I read in some of the SDN forum that SFTP adapter doesnt have the capability to read the files from multiple directories. So, if we get any requirement to read the files from multiple directories using sftP, why could be a possible solution for this requirement?

Thanks for your time. PS.
