Like the video and my favorite webcomic xkcd, I’m also a big advocate of the YYYY-MM-DD date format. I’m also a big fan for DD-MMM-YYYY as in 11-Feb-2014, which I think is even less ambiguous, but it has the huge disadvantage of not being machine sortable. I’m currently in the process of renaming our digitized newspapers so they can conform to these standards. It’s tedious work, but I’m happy knowing that I’m doing my small part to help preserve these records.
Coming back now to the other aspects of file naming, I’m always shocked at the people who are perfectly happy with important documents like membership lists with names like untitled.doc or worksheet(1).xls I try to gently encourage people to give them more descriptive names as best as I can and the reasoning behind doing so, such as, “You might have to find it later!”
