Rename All Files At Once

i know that this is known by many but some of  them don't know this is for those

Imagine you have transferred images from all your devices such as Digital Camera, Mobile, etc. etc. into the same folder!
Everything seems fine, except…the file names…the devices had given a separate name to your image files, and you want them to be one.
Its really simple to rename all files at once.

1. Just select all the files (Ctrl + A) and right-click on the first file and select “Rename…“
2. Rename the first ile and you will notice that all the files have been renamed by that name, ie.mypix.jpg, mypix(1).jpg, mypix(3).jpg…

Was that tough?
You can also use this to rename any other files other than images :)
