What does it mean by command cd /d %~dp0 in Windows [duplicate]

Let’s dissect it. There are three parts:

1. cd — This is change directory command.
2. /d — This switch makes cd change both drive and directory at once. Without it you would have to do cd %~d0 & cd %~p0. (%~d0 Changs active drive, cd %~p0 change the directory).
3. %~dp0 — This can be dissected further into three parts:
   1. %0 — This represents zeroth parameter of your batch script. It expands into the name of the batch file itself.
   2. %~0 — The ~ there strips double quotes (") around the expanded argument.
   3. %dp0 — The d and p there are modifiers of the expansion. The d forces addition of a drive letter and the p adds full path.
