A consistent, human-readable file naming convention helps Web Technologies fix or replace files quickly. It also helps users find and save your files, and for people using screen readers, it can provide valuable information about the file itself.
When you send a file for inclusion on a web page, we may rename it to fit into this naming convention.
One common practice is to use underscores to separate elements, and hyphens to separate words that make up a single element.
Long names add to the file size and may not allow users to save them wherever they need to on their local machines.
But, balance this with the need to help searchers find your file - sometimes the content of your file is not clear if you use an abbreviation.
Especially for living documents, website screenshots, staff photos, or anything else that may receive future updates.
But for time-sensitive material that is unlikely to be updated, including dates may be helpful.
If you must include version information, put it at the very end of the file name.
This can help you keep your files organized on your own machine.
Whatever convention you choose for your own files, use the same one for every file.
