Upload it, then delete it.

I use the ‘Downloads’ folder of my Mac Laptop as my ‘scratch drive’– in which every day, I have my working files there, and at the end of the day or night, I delete them. Same goes with my Desktop (where my screenshots on my laptop are automatically saved) — once I am done, I delete them.

What to do with files you’re not sure what to do with? Just upload them to you WordPress media blog, then delete them.

And when really in doubt, just delete it.
