If you need to batch name files, the Mac’s built-in batch naming tool can greatly improve your productivity.
If you need to rename the image, name it wallpaper and number it consecutionally. Right-click on the image and choose Rename Project. In the Format dropdown on the popup panel, select Name and Index. You can select a number to appear before or after the name in the location drop-down menu, click rename, and the image will be all renamed according to the wallpaper numbered way.
In addition to name and index, you can also rename files with name and count, name and date.
What if we need to change the wallpaper in all filenames to wallpaper? Select Replace text from the Format drop-down menu, enter wallpaper in the Find input box, enter wallpaper in the Replace input box, and click Rename to replace the “wallpaper” in all file names with “wallpaper”.
If you need to add an underscore between “wallpaper” and the number, type “wallpaper” in the Find box, “wallpaper” and an underscore in the Replace box, and click Rename to add an underscore.
If you need to delete the word “wallpaper” in the file name, enter “wallpaper” in the search input box, replace all the words in the input box to delete all, click Rename, the word “wallpaper” will be deleted.
If you want to add the word “wallpaper” back to the file name, select Add Text from the Format drop-down menu, type “wallpaper” in the input box, select Add Before or After the existing name, and click Rename. The word “wallpaper” will be added back to the file name.
The above is the Mac’s own rename tool to use, I hope to help you.
