Deleting files.

I'm trying to make a program that deletes a file called biblio.exe which is in the root dir. I try to accomplish that by first going to the root dir (I think I'm correct) and then opening the file and then using remove.
But it doesnt seem to work, what's wrong?? It says "error en remove".

#include "stdio.h"
#include "stdlib.h"

main(void)
{
FILE *fp;

system("cd..");
system("cd..");
system("cd..");
system("cd..");

if((fp=fopen("biblio.exe","rb"))==NULL){
printf("Error al abrir archivo!");
exit(1);
}

if(remove(fp)) printf("Error en remove!");
}

You are using remove incorrectly.

remove( "myfilename" );

oh and try system("cd \"); to get to the root dir

Why bother?

remove( "c:/myprogram.exe" );

Although to be fair, you could be on another drive than C.

What OS are you trying to do this in? If it is under Windows, i doubt this will ever work, because you have opened this file, and Windows will not allow you to delete any file when it is open or being accessed.
On the other hand, if it is UNIX, you might try:

Code:

---

ret = remove("biblio.exe");
ret = unlink("biblio.exe");

---

If ret is not equal to 0, then 'perror()', you'll know the cause.

It has nothing to do with Windows. His example is wrong because he's passing "remove" a file pointer when it takes a character pointer as an argument.
