Rename files in subdirectories by mask via script in Windows?

Question

cmd/bat

There are files with different names with different extensions in subdirectories like ABC_2018-0n0n-nnnnnn.* [ABC - file name of arbitrary length, n-different digits]
You need to get ABC.* from them with a recursive traversal of all nested directories.

Answer 2

Renaming option - the script simply cuts off the last 17 characters of the file name. All files in the given directory and its subdirectories are renamed.
Initialize the dirfiles variable with the correct value.

@echo off
SetLocal EnableDelayedExpansion
set "dirfiles=c:\temp\"
for /f "tokens=* delims=" %%a in ('dir /s/b/a-d "%dirfiles%" ') do (
  set "fname=%%~na"
  rename "%%~a" "%%~dpa!fname:~,-17!%%~xa"
)
