I want to change all the folder names in a directory so that they all start with the same 3 digit number. For Example, current folder names are 12345, 23456, 34567. I want to change them to 18045, 18056, 18067, etc. If they were files, I could use ren ???*.* 180*.*. Does anyone know of a similar command for the folders? Thanks for the help.

The following batch performs what you need @Echo Off :: XRDIR.BAT Syntax: XRDir Folder_Name String :: XRDir C:\MyFolder 180 Set Fld=%1 Set Str=%2 For /F %%a in ('Dir /B /AD-H %1') Do Call :REN %%a GoTo :EOF :REN Set RDir=%* Set RDir=%Str%%RDir:~3% Echo Move "%Fld%\%*" "%Fld%\%RDir%" GoTo :EOF Type "XRDir Folder String" where Folder is the directory storing the subfolders to be renamed and String the three characyers to be replaced at the beginninig of folder's name (blanks not allowed in folder's name). Activate the script removing the Echo in front of Move command; do it only when sure it works fine.
