When you upload a document to the Media Library, Sitecore uses the file name to populate the Content Title field.
You can edit the Content Title, but this change is internal only. It does not change the file name, the document URL, or how the document appears on the website. Use Content Title if your team wants a clearer internal label in the Media Library. Editing Content Title does not change: To change the URL or the downloaded file name, you must rename the item and republish in the content tree. Note: Updating the Content Title does not change the file name or affect the link URL.
