I have tried
cd E:
cd "E:\android\webrtc_tutorial"
cd ..
However, i noticed that cd ..
will successfully go up a directory. But I still cant change it to E drive. or the desired directory. (see pic2)
That's a common weird thing with cmd.
to change drive, just write the drive path and ':' to cd into it.
for example. to cd into E
drive, write in the cmd:
E:
and then press enter.
