Does " All my files" contain same files that exist in other favourites? ( documents, downloads) ?

I am trying to move all my files from my MacbookPro to an external hard disk manually. And when i look at the finder app, i can see " All my files" and then i see " Documents" and " Downloads" . And i am not sure if they are just a different way to see the same files or different files are located separaetly.

Example: If i save a text document to "Documents" , would the same exact document be visible for me in " All my files" view? And if i move all the files in "All my files" would i have also moved the files in " Documents " and " Downloads" ?

Sorry for my English , it isnt my native language. I am also a Mac noob.

I am using OS El Captain
