Yup that looks like it'll work...I'll translate..
$folder = "D:\Test\" (creates a reference to the folder under which you want to create more folders)
$name = Import-Csv D:\Test\Test.csv (Opens your CSV file for processing - you need to change it to the path of the CSV)
Foreach ($line in $name) (Read your CSV line-by-line, and for each line, get the folder name, and create it)
{
New-Item -path $folder -Name $line.Name -Type Directory
}
PS that needs to be run IN powershell, not DOS (two different things). If you search for Powershell you will find two options - Powershell itself (just a command prompt), or the Powershell ISE (script editor). Use the ISE for this, paste your code into the top half...fix the paths, then run it with the big PLAY button at the top.
