Renaming files in powershell using the folder name

Question

Using Powershell, I want to rename files in folders by using the name of the folder that the files are in. So in my C:\\temp directory, there are 3 folders called \'aaa\', \'bb

Answer 1

Try this

$dirname = resolve-path . | split-path -leaf
Get-ChildItem -Name | Foreach { Rename-Item $_  ( $dirname + $_ ) }

Be careful not to destroy/delete any of your files. No guarantee.

Answer 2

[IO.Directory]::GetCurrentDirectory().split('\\')[-1] will give you the directory you are in.

Answer 3

This will rename the files and put an underscore ('_') between the folder name and the file name:

Get-ChildItem C:\temp -Filter *.txt -Recurse | Rename-Item -NewName { $_.Directory.Name+'_'+$_.Name}
