Por que o ls -lcomando no WSL retorna arquivos e diretórios que não aparecem no Windows File Explorer ou usando o dircomando cmd?

Captura de tela do Windows File Explorer mostrando arquivos no volume C quando a opção "Mostrar arquivos ocultos" está marcada:
Como você pode ver, o WSL mostra mais arquivos como bootmgr, bootTel.datou pagefile.sysenquanto o dir /a:hcomando mostra mais diretórios do que o File Explorer como Config.Msi, Recoveryou $Recycle.Bin.
Por quê?
Muitos desses itens também possuem o
Satributo (System), que entre outras coisas significa "oculto, mas mais". Você pode vê-los usandodir/aoudir/a:s, ou desativando a opção "Ocultar arquivos protegidos do sistema operacional".
