Today while I was editing some photos I took for a rescue organization I work with, I realized that my image processing software outputs file extensions in ALL CAPS (.JPG) instead of lowercase (.jpg) like I prefer. It’s not a big deal, but I like my file extensions in lowercase.
I wasn’t up to editing 35 files individually, so I took to Google and quickly found this very easy to follow tutorial on how to update the file extensions on all files within the same folder at once with one quick command.
Whether you’re comfortable with computers or not, I suggest you check it out because it’s super easy and may just come in handy one day!
Note regarding Method #1 on the site: The asterisk is a wildcard character which tells the system that any file name ending in the extension you specify should be changed to the new extension you specify.
