Got to love an organisation that fully embraces the file.name, file.name.old, file.name.old2, file.name.old-MonthYear, file.name.backup, file.name.test system of version control!
@mike Do make sure about a third of them live in the same directory, a third in the directory backup/ and a third in the directory old/, some of them having the same name but being different.
Consider this a friendly, local pub. Make yourself at home, bring your friends, have a good time! Meet new people, have a laugh, enjoy the ambience, and the Oxford commas.
