Copying folder structure to location that doesn't exist - powershell

Question

I want to copy a folder, complete with subdirectories, files and files within subdirectories, preserving the structure and create them in a new location that did not previously exist. This is my PowerShell code
Copy-Item c:\development\powershell\folderone\* c:\development\powershell\foldertwo -recurse -Container
Copy-Item c:\development\powershell\folderone\* c:\development\powershell\folderthree -recurse -Container
foldertwo exists and is empty, folderthree does not exist.
If I run the script, the structure is created correctly in foldertwo, however folderthree gets created, but contains only all the files from the entire substructure, all at the root folderthree level. It has not recreated the subfolders within folderone, just put all the files at the root level of folderthree.
What have I done wrong?

Answer 1

Here's a very basic, but fully working and tested example, building on your confirmation above that I understood the issue at-hand:
$folderlist = ("foldertwo", "folderthree")
foreach ($folder in $folderlist)
{
if (!(Test-Path "C:\Development\PowerShell\$folder"))
{
mkdir ("C:\Development\PowerShell\$folder") | Out-Null
}
Copy-Item c:\development\powershell\folderone\* c:\development\powershell\$folder -recurse -Container
}

From what I understand, the question is about recreating the folder structure from [source] to [destination]. As using CmdLets is kind of overkill (and performance loss), I suggest simple batch command that may also be ran in powershell.
xcopy [source] [destination] /T /E
xcopy is a function to copy file and directory trees.
Help provides us info on usefult parameters on the case:
/T Creates directory structure, but does not copy files. Does not
include empty directories or subdirectories. /T /E includes
/E Copies directories and subdirectories, including empty ones.
Same as /S /E. May be used to modify /T.
