I am considering using Find any File. ...I am just concerned that it might get rid of something it shouldn't. I don't always know what is safe to delete and what isn't, and I always trusted the apps to make the right decision. Now I'm concerned.
The only thing that "gets rid of [anything] it shouldn't" is a USER!Neither FAF nor EF makes any decisions about what to delete or retain; all they do is tell you what's there, and whether to delete or retain is your decision, and since you've always (I think) been fastidious about "looking before you leap," I don't think either app presents any danger for you.
