Good morning,

Have updated to a new computer running windows 11.
The following bat file will not work on it.
Lots of googling, there is no longer wmic and that I must use powershell. Looking at many posts on stackoverflow.com I still dont get it.
Please write me something I can put in a batch file.

Sun 01/18/2026 10:14:23 C:\tmp >cpdas aaa.txt

Sun 01/18/2026 10:14:23 C:\tmp >copy "aaa.txt" "C:\tmp\aaa-20260118-1014-23.txt"
1 file(s) copied.
Sun 01/18/2026 10:14:23 C:\tmp >

8<--- old script

@echo off
for /f "tokens=2 delims==" %%I in ('wmic os get localdatetime /format:list') do set datetime=%%I
set datetime=%datetime:~0,8%-%datetime:~8,4%-%datetime:~12,2%
@echo on

copy "%1" "%~dpn1-%datetime%%~x1"

8

Thanks,

wmic will still work in Windows 11, they just made it an optional
component that you can still add back. Here's how:

My google research says it was dropped for security reasons. I am going to try for a powershell script.

Thanks,

Replace

| > /format:list') do set datetime=%%I

by

set datetime=%date%%time%


and replace 0,8 8,4 ...

| > set datetime=%datetime:~0,8%-%datetime:~8,4%-%datetime:~12,2%

by the correct values for your %date%%time% format.

Good morning,

set datetime=%date%%time%
copy "%1" "%~dpn1-%datetime%%~x1"


01/21 2:08 C:\tmp>batch aaa.txt

01/21 2:08 C:\tmp>set datetime=01/21/26 2:08:16.24

01/21 2:08 C:\tmp>copy "aaa.txt" "C:\tmp\aaa-01/21/26 2:08:16.24.txt"
The filename, directory name, or volume label syntax is incorrect.
0 file(s) copied.


Date is backwards, should be 20260121
Slashes are causing it to fail
Need white space : . to be replaced with a -

Thanks,

If this is your date/time format, try:

:newday
set d=%date%
set t=%time%
if not %d%==%date% goto :newday

set datetime=20%d:~6,2%%d:~0,2%%d:~3,2%-%t:~0,2%%t:~3,2%%t:~6,2%
set datetime=%datetime: =0%
echo %datetime%

Or change your date format to ISO std!

Bah, and indeed Humbug.

PowerShell can run commands on its command line, so you can use
PowerShell as a standalone executable, similar to how you used WMIC
before:

for /F %%n in ('powershell -command Get-Date -Format
"yyyyMMdd-hhmm-ss"') do set datetime=%%n
