Hi there and welcome,
apologies, I didn't see this post !
The best Data Recovery Software that I know/use for the Mac is
DataRescue II
There is no software built in or included with OS X to allow you to recover the folder. You would need to use something like DataRescue.
There is a demo that you can download on their website.
You do need an external drive though to use it though, it needs somewhere to recover the data to.
regards
Ric
