There have been questions about the old
sdcard turning into
sdcard0, which I understand to be part of the multiuser feature.
What I don't understand is the 3 paths in the questions. Some of them look like symlinks to me, since files copied to one place show up in another.
Could anyone systematically explain the relationship between those 3 (and any other storage path)? Given that relationship, where should I store my files (e.g. Firefox's Download location, Aldiko's ebook storage directory, etc.)?
