How to Name Files
Do Not Use Special Characters
For best results, you should only use the letters a-z, A-Z, the numbers 0-9, hyphens (-), underscores (_) and periods (.). Any other character could get you in trouble, causing the file not to load or the page to load incorrectly.
it is best to use lowercase letters, also Do Not Use Any Spaces
