-------------------------------------
> for /f "tokens=1,2 delims==" %A in ("a.txt")
This will parse the literal string "a.txt", the spaces in the string is ok.
> for /f "usebackq tokens=1,2 delims==" %A in ("a.txt")
This will parse the content in file a.txt, space in the path is ok.
> for /f "usebackq tokens=1,2 delims==" %A in (a.txt)
This will parse the content in file a.txt, the path must not contain spaces.
