Windows 10: Renaming of many files.

I have done it before, but cannot remember what to do.
I have a bunch of pictures from the Grand Canyon, taken on different cameras and cell phones.
All have differed names and I would like to make them all the same like:
change from: img_001_dgep.jpg and so on
to: GC2014_1.jpg, GC2014_2.jpg and so on.
I know there is a simple way of doing it, but I can’t remember how.
Anyone?

Thanks
Sven

Renaming group of files

Powershell would look a bit like this:

cd $env:userprofile\AppData\Local\Packages\Microsoft.Windows.ContentDeliveryManager_cw5n1h2txyewy\LocalState\Assets

New-Item -ItemType directory -path $env:userprofile\desktop\ -Name new_images -Force

Get-ChildItem * |Copy-Item -destination "$env:userprofile\Desktop\new_images"

cd $env:userprofile\desktop\new_images

$names = Get-ChildItem *

foreach($name in $names)

{

Rename-Item -Path $name -NewName "$name.jpg"

}

 

upgrade windows10 leaves many files renamed...is there?

Greetings

is there any way to remove the additional filename addition after upgrading to Win10?

filename rename formula or batch file etc...?

underlined portion is an example of the portion of the file adding in the rename?

The original file name remains intact except for the middle portion.

originalfilename.d20140908-u041050.xxx

I can do it manually but I have 13 gigs of docs let alone software archive.

Appreciate anyone's time, help and resolutions.

 

Test this first (I just did but you should confirm):
In a command prompt, use the command: rename img*.txt GC2014*.txt
Make sure you're in the correct directory in the command prompt.

 

I just remembered,
select all files and then rename the first file to what you want. any file after that will have the same name with a (1), (2) aso behind it.
