#Rename a group of folders after files in those folders, using a regex?

I have a massive set of folders all containing files with the same file extensions - ".mod." The folders are named randomly with strings of numbers, but I would like to name the folders each after the name of the ".mod" file in the folder, then remove the ".mod" file extension from the name of the folder itself. How could I implement this using a Powershell script?

#

In other words, I'd like to rename folders by matching the name of the folders to files within them, which have the ".mod" extension.

#

for /d %%a in (*) do (
for %%b in ("%%a*.txt") do (
ECHO ren "%%a" "%%~nb"
)
)

I found this batch script which appears to do what I want if I replace .txt with .mod, but how do I avoid it recursively going over the subfolders inside those folders?

Without examples it's hard to know what you exactly want.

Try this to preview names, without actually editing anything

$all_mods = gci -Path '.' -Filter '*.mod' -File -Recurse
$new_names = $all_mods | %{ 
  [pscustomobject]@{
      Name   = $_.Name
      Parent = $_.Directory.FullName
      NewName  = Join-Path $_.Directory.Parent $_.Name
      NewName2 = Join-Path $_.Directory.Parent.FullName $_.BaseName
  }
}
$new_names|fl
$new_names| Out-GridView
#

Or show the examples of the full filepaths for a few before, and after cases

current file structure looks like this

12345
└── Alpha.mod
23456
└── Beta.mod

and desired structure

Alpha
└── Alpha.mod
Beta
└── Beta.mod

right?
