And THAT is why I personally quit using File a long time ago. I encourage you to take a close look at Pathname, which I found put the various methods where I thought they should have been in the first place.

=> "file.ext"

delete, .dirname, .atime, .executable?, .exists?, .extname, and on and on are properties of specific files, so having the methods on the instance, instead of the class, just makes all kinds of sense to me.

Pathname only has three class methods, including new. Vastly more intuitive to me.
