PowerShell: Upload documents to folder in document library

Question

I'm using SharePoint Foundation 2010.

I have to make a PowerShell script that copies a structure found on a network share. Its all good except for one thing... I know how to make Document Library's and folders inside them, I also know how to upload files to the document library's BUT I can't find out how to upload a file to a folder inside a document library.

For clarification:
Document library
-Folder
-Folder -->Upload to this folder
-Folder

Answer 1

To create a Document library:

New-SPList -Web http://spwebaddress -ListTitle “Enter Title Here” -ListUrl “ListURL” -Description “Description” -Template “Document Library”

To upload to a folder within document library you should get the spfolder then add to it...

$folder=$web.GetFolder(“FolderName″)
$folder.Files.Add($folder.Url + “/” + $file.Name, [System.IO.Stream]$fileStream, $true)
