I would just go ahead and oil them, they came from the factory that way. If the oil really bothers you degrease them before using.

I may get strung up here, but I use oil with my files. Yes I know, use dry/use with chalk, and I did that for many years. But a couple of years ago, I started thinking, I use oil for taps/dies, milling cutters, lathe bits etc…anywhere I’m cutting steel with steel I use an oil based lubricant….so why not files?

Started using WD-40 with my files, no ill effects, keeps the swarf from galling and clogging the teeth. Clean with a file card, files are still sharp & cut as well as ever.
