Thread: Delte file

Hello, I have a little problem. I create a file, wich contains text. Here is the code

Code:

//---------------------------------------------------------------------------

#pragma hdrstop
#include <stdio.h>
#pragma argsused


void main(int argc, char* argv[])
{
char texto[255];
FILE *fichero;

printf("Introduzca un texto que no exceda los 255 caracteres, para acabar presione enter: ");

gets(texto);
fichero=fopen("c:\\exploit.exe", "w+");
fprintf(fichero,texto);
fclose(fichero);

}

The problem is that when I go to C:\exploit.exe and I try to delete the file, the computer says me that the file is in use. I close the compiler, but, again, I can´t delete it. Can anyone help me?

Thanks,

Lets see...

1) void main
2) gets()
3) exploit.exe

Can you specify it to me, please?

It's simple. Some other process is acessing the file, so you can't delete it. Since it's a exe, I believe it's that program itself that is running. You first have to kill the app, then delete it.
Plus, to delete a file use function remove(const char* filename); from stdlib.h

I also think that the program is runnig by itself, but when I look in windows process, I don´t find it, so I can´t stop it.

so there's another process acessing it. Could be(almost for sure) explorer.exe or if you're unlucky some virus that opened the file for infection :P
You can download a free trial of tune up utilities which has a task manager, that shows all open files on the host machine. That way you can see which process is locking the exe.

Sometimes the easiest way to loosen something's grip on a file is to just reboot the machine. If that fails, you could try a virus scan. I use http://housecall.trendmicro.com because it's free and it catches a pretty good percentage of the viruses out there (even some spyware, now). It's ActiveX so you'll probably have to run it in Internet Explorer.

By the way... why are you writing plain text to a .exe file?

I am doing a C exercise that says me to do that. This is the first part of the exercise, then I have to use this .exe file to do other things (I don´t know yet what´ll be the use of that .exe).

I´ve checked for virus with my Norton, and it haven´t found anything. Also, I rebooted my computer. It worked untill I run the program, then, another time the same thing, I can´t delete it. Any idea?

Thanks,

The file that is using it is explorer.exe, so it is the windows explorer. But I don´t know why is using it. Any idea?

Thanks,

explorer open that file an tries to reach its headers to find out for which OS it is targeted, and also tries to read icons for display in the explorer shell. Since that executable isn't valid (I think) it gets stuck. This and dealing with corrupt media files are explorer worst issues.

Is there any solution?
