A Mac has one disk with a name instead of a letter: Macintosh HD, written / in paths. Everything hangs off it, with forward slashes:
| On Windows | On a Mac | Notes |
|---|---|---|
C:\ | / | Macintosh HD. Hidden from the Finder sidebar by default; Finder → Settings → Sidebar shows it. |
C:\Users\you | /Users/you, written ~ | Your home folder: Desktop, Documents, Downloads, Pictures, Music, Movies. |
C:\Program Files | /Applications | Each app is one file that looks like a folder inside. |
%APPDATA%, %LOCALAPPDATA% | ~/Library | Hidden by default. Hold ⌥ and open Finder's Go menu to see it. |
C:\Windows | /System | Read-only. You will never need to go there. |
D:\, USB drives | /Volumes/Name | Every other disk appears here, and on the Desktop if you let it. |
| Recycle Bin | Trash, at the right end of the Dock |
The Finder sidebar is the Quick access list: drag any folder there. To see where you are, turn on the path bar (View → Show Path Bar); double-click any segment of it to jump there.
