Welcome to Android Central! You don't remember your own wi-fi password, or is this a password to someone else's network?

1. /data/misc/wifi probably doesn't exist.

2. To get to any folder in /data (nothing in /data is accessible without root), you have to:

adb shell "su -c cat /data/<wherever the file is>/wpa_supplicant.conf" > c:/wpa_supplicant.conf

(You'll have to find where the wpa_supplicant.conf is kept. [It's possible that Samsung put it in /data/misc/wifi/ - Google didn't. There's no wifi folder in my /data folder in my Pixel 2.])
