cd command not working. Cant change directory in windows 10

Question

I was using the cd command to switch my drive to E: which basically contains all my junk files which I use for experimentation but the problem was cd was not working. The command I used was

cd E:  
ren *.* *.bat

However the time I ran this batch file (typed in notepad saved with a .bat extension) it didn't work out the cd command and ended up renaming all my desktop. When I tries using it in the command windows the result is

cd E:
E:\

then nothing what should I do.

Answer 1

In order to change to a different drive you either have to add the /D parameter to cd or type the drive on a line by it's own.

cd /D E:\

Or

E:
