Rename a file in Dos to datestamp??

[Derek]

What is the syntax used in a batch file to rename a file
to the file's creation time/date in WinXP? Alternatively,
even renaming to the current system time/date would do?

I have tried searching for this, but have drawn a blank.

Your advice would be appreciated!

Thanks

Derek

These snippets should help

FOR %A IN (*.jpg) DO ren "%A" "GMV3535.%~nA%~xA"

Will change all jpg files in a folder to GMV3535.<original name>.jpg

The case of the A (as in %A or %~<letter>A) is important. FOR/IN/DO is =
uppercase to highlight the actual command syntax.=20

Windows help has all the info

I went and did the hard work for you, but it can be optimised. As this =
is so boring I was leaving optimisation to you.

@echo off
echo. |date>date.txt
FOR /F "eol=3DE tokens=3D4,5,6,7,8* delims=3D/, " %%i in (date.txt) do =
Set Z=3D%%k-%%l-%%m
move "%~1" "%~1%Z%"
del date.txt

Make a batch file with these lines in it, drop a folder on it, folder =
renamed.

New Folder becomes New Folder01-12-2003

many thanks. only problem is this adds the date to the end
of any filename, so the file extension is effectively
lost. don't suppose you know how to add it to the start??

thanks

Yes I just don't know exactly how you are going to use this.

Should do it. %Z% contains the date in a legal filename format (no /)
move "%~1" "%Z%%~1"

Type for /? and look for all the %~<variable> to see how to pull parts =
out of a filename.
..
