Best Practices for File Names and URLs

• Ditch the junk: No underscores, weird characters, or spaces in your file names or URLs. Just don't.

• Dashes are your friends: Use dashes instead of spaces. They're totally fine. Search engines recognize them as word separators.

• Capitalization counts (sometimes): Title casing is cool for file names like "Document.pdf" or "Video.mp4," but keep extended URLs all lowercase (like "jesusfilm.org/watch," not "jesusfilm.org/Watch").

• Version it up: Even if you think it's the final version, slap a version number on it. You never know!

• Think like a downloader: Name files in a way that someone searching for it in the future will be able to find it.

• Maybe add "JFP" at the start.

• Throw in the year at the beginning or end, too.

• Why all the rules? Mostly for SEO (search engine optimization), but also to avoid links looking weird and to prevent issues with older browsers. Plus, keeps things tidy.

• Internal vs. Public: You might get away with anything for internal stuff, but sticking to best practices saves headaches later, especially if you plan to share files publicly.
