Create directory using batch file

     In the following tutorial explain you to create more directory using DOS command through batch files (.bat), you can create 100 of folder (directory) in double click.

Steps:
  1) First you need to set echo off for hide the parent directory.
  2) Pause command is used to pause the execution temporary.
  3) Set statement is used to assign a value to variable (eg: set a=1)
  4) If statement is used to check the condition and continue the execution, else then execute from the next line (eg: if %a% LSS 31 md %a%)
 Conditions are check using the following method

               EQU : Equal
                NEQ : Not equal

                LSS : Less than <
                LEQ : Less than or Equal <=

                GTR : Greater than >
                GEQ : Greater than or equal >=

                This 3 digit syntax is necessary because the > and <
                symbols are recognized as redirection operators

5) Goto is used to transfer the execution to another label.

The code is

echo off
pause
set a=1;
set b=30;
echo %b%
:Rept
if %a% LSS 31 md %a%
 set /a a+=1
if %a% LSS 31 goto Rept
cls
set /a a-=1
echo                           %a% Directory Created Successfully
pause
