For that, the %TIMESTAMP% syntax does not help.

See this article for all the options you have:

How do you get that to work for a previous day to select a directory? So if I logged onto the FTP site right now the most recent directory is 03302016 and the files inside of that directory have a date/time stamp of today.

Use get %TIMESTAMP#yyyymmdd%/*

See https://winscp.net/eng/docs/scripting#timestamp

I'm looking for help with writing the proper syntax to download files from a folder on a FTP site that is stored in folders by date.

The folder structure is as follows:

03212016
03222016
03232016
03242016

The files inside of each folder have a date/time stamp of the calendar day that follows. i.e. folder 03212016 has files with a date/time stamp of 03222016hhmmss



What's the proper script to write to automate the process so I can have WinSCP download the files from the correct folder each day?

Thanks
