I updated the script written by "Nico Martens" in below blog post

http://sharepointrelated.com/2014/11/11/download-all-content-in-a-site-collection/

Below script will download all your documents in specific folder of Site and List

Save this script as Get-SPContent.ps1 and run using below line

.\Get-SPContent.ps1 -SiteCollection "<SiteCollectionURL>" -Destination "<Path>"

[Parameter(Mandatory=$true)]
[ValidateScript({asnp *sh* -EA SilentlyContinue;if (Get-SPSite $_){$true}else{Throw "Site collection $_ does not exist"}})]
