filename - "an identifying name given to a computer file"
The best file naming format is: "tag1 tag2 tag3 ... title.ext"
Folders are only used for the higher truth of files.

Edit
Citizens who post at Futaba-style imageboards are known to attach image or video files with clever filenames. For example, an anon uploaded a video file of a person who sort of dodged a truck that turned left into the road he was walking on. About one second later in the video the gate or door on the back of that truck swung open and hit the person in the head. The anonymous user named the file "final_destination.webm" in reference to the Final Destination movie in which people's destiny of death is unavoidable.
Alternatives to /:*?"<>| Edit
Apparently, some of the characters below have died:
