c program to make password protected folder

This is a program to open any folder in c drive in which you have set a password...


 #include<stdio.h>
 #include<conio.h>
 #include<string.h>
 #include<stdlib.h>
 #include<process.h>
 int main()
 {
    char string1[20]="abcdefgh";
    char string2[20];
    int i;
    printf(" enter password for the notepad file that you want to open \n ");
    gets(string2);
    i=strcmp(string1,string2);
    if(i==0)
     {
      printf(" password is correct ");
      system(" explorer c:\\bluej ");
     }
    else
    printf(" invalid password enter the correct password ");
getch();
}
Here, the program is written in dev c++ instead of void , int main() is used...."abcdefgh" is the password name and "bluej" is the folder you want to open..you can write any other folder name and give any other password....
and note that the folder which you want to protect by password has to be hidden
to do that ..........
  1) right click on the folder icon
  2) go to properties
  3) under the general tab click on hidden tab.........

if you have any problem or suggestion your comments are invited.....
