Copy specific type files from subfolders using a Powershell script

Question

I have many folders, some of which have subfolders. I want to find and copy to special directory all files of one type, for example .txt, from them. I use this script and it works, but it copies all folders on the way to my file too. How can I avoid this? I thought about deleting all empty folders after copying, but I'm sure that the more right way exists.

$folders = [IO.Directory]::GetDirectories("S:\other","*","AllDirectories")

Foreach ($dir in $folders) {
    Copy-Item -Path $dir -Filter *.txt -Recurse -Destination 'D:\FinishFolder'
}

Answer 1

使用Get-ChildItem发现文件，然后Get-ChildItem复制它们：

Get-ChildItem S:\other -Filter *.txt -Recurse |Copy-Item -Destination 'D:\FinishFolder'
