Rename using batch file folders with dot-CodePudding

I have a lot of folders and files with the same prefix and at the end of the perfix there is a dot, for example : ProjectName.Data

I failed to rename using batch file. I want to rename from "ProjectName.*" to user input (which defines the actuallty project name, and save the characters after the dot) for example. if the input is "newProject", that from ProjectName.Data --> newProject.Data

I wrote:

@echo off

echo What is your project name?

set /p PROJECTNAME=

for /r %%j in (ProjectName.*) do ren "%%j" "%PROJECTNAME%.*"

What is the problem?

CodePudding user response：

for /d /r %%j in (ProjectName.*) DO ren "%%j" "%PROJECTNAME%%%~xj"

worked for me.
