Question : PowerShell SFTP

Hello,

I am looking to automate SFTP transfers from a vendor.  This would be simple by using psftp.exe if I were grabbing the contents of the entire directory daily, however the data will remain on the SFTP server for 1 - 2 weeks, and I will need to check a few other things before downloading the files.  The files are large so I do not want to overwrite daily.

The /n tools are not an option as I have 0 budget for this project.  Is there any other way to SFTP through PowerShell that is free, and that I would have the ability to check if files had already been downloaded by comparing against a text log of previously downloaded files?  It has to be against a list, as the files will be transfered out of the temporary download location daily.

If there is no way to do this through PowerShell, but you are aware of other options, I am open to all ideas.

Thank you for any information / ideas.
