I'm having a surprising amount of difficulty searching for an answer to this seemingly simple question. I came across an article on MSDN titled "Naming Files, Paths, and Namespaces", which whilst edifying, did not answer answer my question (unless I'm just failing to make the right connections).
- "My Documents" is a symbolic link/reparse point to any folder you specify. When using File Explorer to browse the directory in which the folder is contained, the folder is still shown as "My Documents" regardless of the actual folder name.
- "iCloud Drive" is actually "iCloudDrive".
- Within iCloudDrive, "Pages" is actually "com~apple~Pages".
