there is nothing more redundant then using .file as a file extension

Please refer to your username as my response to this

Edit: I can actually understand why you would make it .file though, some languages will actually consider a file without an extension a directory and won't actually allow the file to be found (yes it's stupid I know)

file.dot is redundant as well.

@arcadesdude why? Aren't they for DOT

@phorkyas dot dot.

Would you prefer the inode as filename?

file.dot.extension
