Thanks for a good question.
WordPress needs a unique name (also called a slug) for every post, page and Media Library item in the database. It also needs a unique filename for every item uploaded to the same directory.
Titles, on the other hand, do not need to be unique and can even be completely empty. Once an item is uploaded you can edit the Title to make it more attractive or descriptive.
If your items have unique, lowercase names without embedded spaces the Title and Name values will be the same.
To generate unique names WordPress will append a number as needed to get a unique value. It also “clean up” names/slugs, making all the letters lowercase, removing special characters and replacing spaces with dashes.
Try uploading the same file two or more times and you will see these rules in action.
I hope that answers your question. I am marking this topic “Not a Support Question” since it is not MLA specific. Please update it if you have any further questions about Name and Title values in WordPress. Thanks for you interest in the plugin.
