Notes: If you just upload a file with a space in it, or some other special character, your file names can get uglyâ€¦ Spaces will turn into %20 for example. Uppercase letters can also complicate matters, since many web servers are case-sensitive. With this action youâ€™ll get friendly, pretty URLs every time.
