I know that Chrome OS doesn't have an inherent "merge" option (even though it SHOULD), so are there any alternative file explorers that do? I'm trying to merge 2 folders that have a LOT of sub-folders and files, and I really don't want to mess something up by copying everything over individually and then accidentally deleting the ones I want to keep.

Yes, I know there was another post about this posted 5 years ago, but the question never got properly answered. I'd really appreciate it if you guys would answer this one, please!

And if your answer involves the Terminal, please give me a list of commands as part of your answer because I'm still very much a beginner with using it.
