Why is there so many identical Android folders? I was using the ES File Explorer app, when I noticed there's many different folders with all the same content. Like, there's a "legacy" folder, a "0" folder, and an "sdcard" folder, and it all goes to the same place where my DCIM is and such. I'm wondering if whatever I have takes up three times the space, or its all shortcuts to the same place. I'm confused with all this folder nonsense.
Because of how Android has evolved over the years many newer devices have the same files mounted (usually with a bind mount) in multiple places. Others are symbolic links. It's really too bad that the file manager app isn't showing you these details :-/
