Basename, Filename, Dirname in Batch

Umm, batch scripts sucks, but here goes:

set filepath="C:\some path\having spaces.txt"

for /F "delims=" %%i in (%filepath%) do set dirname="%%~dpi" 
for /F "delims=" %%i in (%filepath%) do set filename="%%~nxi"
for /F "delims=" %%i in (%filepath%) do set basename="%%~ni"

echo %dirname%
echo %filename%
echo %basename%

I have awed this for crap many times before, now I have it here for the future.
