rename files with in a directory appending date&time

[Thushyaa]

Hi ,

I am looking for a way to rename all files that are in a directory with a simple append at the end with date and time.

eg:

file1 -> file1ddmmyyhhmi

file2 -> file1ddmmyyhhmi

eg:

$A=get-date -Format "yyyymmddhhmm"

foreach -object -process ....

thanks.

You could try something like this

$A=get-date -Format "yyyymmddhhmm"
Get-ChildItem "C:\folder" | %{
	Rename-Item -NewName ($_.Basename + $A + $_.extension) -Path $_.FullName
}

This assumes the files are stored in C:\folder

LucD - thx for the fast response ,

how can i use this with multiple items in the directory ? it works if there is only one file. how to use foreach ? etc...

Are you sure ?

I tested it on a folder with multiple files in there, and they were all renamed.

Are you sure there are no 'hidden' files in the folder ?

This is a test run I just did

PS C:\> Get-ChildItem "C:\folder"


    Directory: C:\folder


Mode                LastWriteTime     Length Name
----                -------------     ------ ----
-a---         10/8/2010   3:22 AM          0 abc.txt
-a---         10/8/2010   3:22 AM          0 pqr.txt
-a---         10/8/2010   3:22 AM          0 xyz.txt


PS C:\> Get-ChildItem "C:\folder" | %{Rename-Item -NewName ($_.Basename + $A + $_.extension) -Path $_.FullName}
PS C:\> Get-ChildItem "C:\folder"


    Directory: C:\folder


Mode                LastWriteTime     Length Name
----                -------------     ------ ----
-a---         10/8/2010   3:22 AM          0 abc201053080953.txt
-a---         10/8/2010   3:22 AM          0 pqr201053080953.txt
-a---         10/8/2010   3:22 AM          0 xyz201053080953.txt


PS C:\>

You could to a

Get-ChildItem "C:\folder" -Force

to check.
