Every time you download photos from a camera or mobile phone on Windows, you are faced with a list of encoded file names. To easily know the subject of these photos, the simplest solution is to rename them, a task that requires a long time.

A common drawback in older versions of Windows was the inability to have two files with the same name in the same location. Since Vista, Windows automatically adds a counter if two files or folders have the same name.
You can use this technique to your advantage and easily rename multiple files at once while counting them. Of course, it can also be done with separate third-party applications that offer more functionality, but we will show you how using pure Windows commands.
So let's go:
Step 1: Place all the files you want to rename into a single folder.
Step 2: Select all the files in the folder with your mouse (or simply by pressing Ctrl + A).
Step 3: Right-click your mouse and go to the “Rename” command (or simply press the F2 key to edit one of all the names).
Step 4: Rename the file as you wish and then press “Enter” to rename the rest.

As a result, all files will be renamed to the name you want with an additional counter of the type (#) at the end of the name, where # is a number – file counter.
You can simply insert additional characters into the existing name to also preserve the original. The combinations are unlimited and give you full control over the renaming options.
