Either of those is acceptable, Angela, as are the suggestions made by Mafe Dongo and shoobydoowap...Hi,
There are many files. I need to classify them and maybe adjust the layout of some files. To describe this meaning, could I say "I will clean up my files" or "tidy up my files".
Hope I express my question clearly.
I would probably use the verb "organize," as in "I'm going to organize my files." I think you could say "I'm going to clean up my files," but I think that would have more to do with the physical appearance of them--if paper is sticking out, they're all scattered around your desk, etc.
Hmm... I hope that's helpful. I'm new to this forum, so I hope someone else can give you a second opinion.
