Is there any advantage or disadvantage to naming files (for sharing) like these examples:
The Keys to the Kingdom.mkv
The_Keys_to_the_Kingdom.mkv
The.Keys.to.the.Kingdom.mkv
I see these on FTP sites and other similar places.
There is no practical difference in any file name. As long as the name is valid, the computer don't cares at all and software will just work. Use the one that suits you better.
The only caveat I found is with names with spaces. When refering to those, the command lines including those must be enclosed in quotes to avoid trouble, but once the quoting is in place, they work the same as anything else.
Spaces are OK if the file is in a zip or rar (eg to include subtitles or extra info), otherwise the convention is periods not spaces. Whilst Windows can use spaces, stuff online goes through many platforms and OS's (eg Linux, Unix), and somewhere down the line a space may cause a problem.
