#include <stdio.h>
#include <stdlib.h>
#include <conio.h>
int main ()
{
int i,j;
puts ("Trying to execute command CD ");
i = system ("cd c:\text");
if (i==-1) puts ("Error executing CD");
else puts ("Command successfully executed");
puts ("Trying to execute command del ");
j = system ("del *.txt");
if (j==-1) puts ("Error executing del");
else puts ("Command successfully executed");
getchar();
return 0;
}It won't work. How do I make this go to a specific directory? I know if i just make it i = system ("cd"); that it will print the current directory. Is there a way to change directories this way?

system actually starts a new process, does what you want, then closes that process. in fact, if you really think about it, what does it mean to "change directory"; "change directory" or cd is a Shell implemented feature on the *system* level. With this in mind, you're best bet is to use the standard unix library.
#include <unistd.h>
and the function chdir(char *path)
man chdir
man getcwd
system is the worst function of all time, never use it.

I'm sorry, at a closer look you are using Windows...I thought you were actually using C on a Unix System. I'm not sure how you'd do it with the Win32 API, I'd imagine it is quite similar.
