This should work for you  IF NOT EXIST  quot  path to your folder quot  md  path to your folder  However  there is another method  but it may not be 100  useful  md  path to your folder  gt NUL 2 gt NUL  This one creates the folder  but does not show the error output if folder exists  I highly recommend that you use the first one  The second one is if you have problems with the other

You can use   if not exist  C  VTS   mkdir  C  VTS    You can also expand the code to replace any missing expected files   if not exist  C  VTS important file  echo   gt   C  VTS important file

I use this way  you should put a backslash at the end of the directory name to avoid that place exists in a file without extension with the same name as the directory you specified  never use  C  VTS  because it can a file exists with the name  VTS  saved in  C   partition  the correct way is to use  C  VTS    check out the backslash after the VTS  so is the right way    echo off  break off  title Create folder with batch but only if it doesn t already exist - D3F4ULT  color 0a  cls  setlocal EnableDelayedExpansion  if not exist  C  VTS       mkdir  C  VTS     if   errorlevel   EQU  0        echo Folder created successfully     else       echo Error while creating folder       else     echo Folder already exists    pause exit

Just call mkdir C  VTS no matter what   It will simply report that the subdirectory already exists   Edit  As others have noted  this does set the  ERRORLEVEL  if the folder already exists  If your batch  or any processes calling it  doesn t care about the error level  this method works nicely  Since the question made no mention of avoiding the error level  this answer is perfectly valid  It fulfills the needs of creating the folder if it doesn t exist  and it doesn t overwrite the contents of an existing folder  Otherwise follow Martin Schapendonk s answer

You just use this  if not exist  C  VTS   mkdir C  VTS it wll create a directory only if the folder does not exist   Note that this existence test will return true only if VTS exists and is a directory   If it is not there  or is there as a file  the mkdir command will run  and should cause an error   You might want to check for whether VTS exists as a file as well
