    c1 = -1;
    while (c1 == -1)

       strcpy(t5c, t5d);
       sprintf(temp, "%d", c3);

       c1 = _mkdir(t5c);
       c3++;
      }
      strcat(t5c,"\\7zip.7z");


it get stuck in the loop.
after the first pass
the first pass when c3=0 is ok
then it go thru my code
and wont create directory #1

the debugger shows the string ok

Line 46 calls _mkdir() instead of mkdir(). What's the difference?

You can probable get the system to tell you exactly why mkdir failed by printing the value of errno afterwards:

1
2
3
4
5
6
#include <cerrno>
...
c1= mkdir(t5c);
if (c1) {
    cout << "mkdir("<<t5c <<") failed: " strerror(errno) << '\n';
}

strcat(t5d, "D:\\output\\"); should be strcpy
I never cleard t5d

dumb mistake
