Check if drive letter exists in batch, or else goto another piece of code

Question

I'm trying to make a code that detects if a drive letter exists.

For example, to check if C: drive exists my code is:

@echo off title If Exist Test  :main CLS echo. echo press any key to see if drive C:\ exists echo. pause>nul IF EXIST C:\ GOTO yes ELSE GOTO no  :yes cls echo yes pause>nul exit  :no cls pause>nul exit 

But it doesn't work, it either goes to :yes if C: exists or shoes a blank screen if doesn't. What am I doing wrong, so that it won't go to :no?

Answer 1

The main problem in your code is the if ... else syntax. The full command needs to be read/parsed as a single block of code. It does not mean that it should be written in a single line, but if it is not, the lines must include information to the parser so it knows the command continues on the next line

if exist c:\ ( echo exists ) else ( echo does not exist)  ----  if exist c:\ (     echo exists ) else echo does not exist  ----  if exist c:\ ( echo exists ) else echo does not exist  ----  if exist c:\ (     echo exists ) else (     echo does not exist ) 

Any of the previous codes will work as intended.

Anyway, the checking for the root folder of the drive will generate a popup for some kind of drives (in my case it was the multi card reader). To avoid it, use instead the vol command and check for errorlevel

vol w: >nul 2>nul if errorlevel 1 (     echo IT DOES NOT EXIST ) else (     echo IT EXISTS )

@echo off title If Exist Test  :main CLS echo. echo press any key to see if drive C:\ exists echo. pause>nul ::NB: you need the brackets around the statement so that the file  ::knows that the GOTO is the only statement to run if the statement  ::evaluates to true, and the ELSE is separate to that. IF EXIST C:\ (GOTO yes) ELSE (GOTO no)  ::I added this to help you see where the code just runs on to the ::next line instead of obeying your goto statements echo no man's land  :yes ::cls echo yes pause>nul exit  :no ::cls echo no pause>nul exit
