    Messing with folders

    Hello c++ people!
    Well... Have you guys ever seen when you right click on a folder and see it proprieties?
    I want to make a program that will check for the folders in a root (for example: folder 1, folder 2, folder 3) and will save in a file the folder info (like how much files there is inside the folder, the total size of the folder, etc...)
    How do i do that? Thanks ^^

    Well, you'll need to access the folders nd files in them, and that's a little bit platform-dependant. You can use POSIX opendir(), readdir() etc if you have them, and stat() to get file properties. If you're on Windows I'm sure there are loads of directory handling functions you can use; refer to MSDN.

    But if you want my honest opinion, the quickest, easiest way to do this is to dump C++ altogether and use #!/bin/sh or whatever else your system provides.
    Code:
    #include <stdio.h>
    
    void J(char*a){int f,i=0,c='1';for(;a[i]!='0';++i)if(i==81){
    puts(a);return;}for(;c<='9';++c){for(f=0;f<9;++f)if(a[i-i%27+i%9
    /3*3+f/3*9+f%3]==c||a[i%9+f*9]==c||a[i-i%9+f]==c)goto e;a[i]=c;J(a);a[i]
    ='0';e:;}}int main(int c,char**v){int t=0;if(c>1){for(;v[1][
    t];++t);if(t==81){J(v[1]);return 0;}}puts("sudoku [0-9]{81}");return 1;}

    There's an FAQ on the subject: http://faq.cprogramming.com/cgi-bin/...&id=1044780608

    I want to make a program that will check for the folders in a root (for example: folder 1, folder 2, folder 3) and will save in a file the folder info (like how much files there is inside the folder, the total size of the folder, etc...)
    Like this? (All files.)
    Code:
    $ stat `ls *` >> folderinfo
    or this? (Directories only.)
    Code:
    #!/usr/bin/perl
    
    foreach(<*>) {
        if(-d) system("stat $_ >> folderinfo");
    }
    or this? (DOS folder-only listing.)
    Code:
    dir /ad /b > folderinfo.tmp
    dwk
