To perform a super-fast full system search for any file, a great alternative is Everything: Those paths highlighted in yellow, namely those at \WindowsApps and \Python310, would be ideal candidates to add to PATH because they look like executables at the root level of an installation. escape('//?/c:/Quo vadis?.txt') returns '//?/c:/Quo vadis[?].txt'. Thus, we need to begin in the root of the file system and navigate through the folders given by name, whereas the names are separated by /s (because this is the unix path separator).
