Help needed in regarding to deletion of a file......

[palani12kumar]

Hi every body.
i'd write a program to copy the content of one file to another file and to delete the content of the first file. But after deleting the first file remains the harddisk(even though it has no data in it). i want to remove the file totally from the harddisk. How to implement this. I'd written the program in C and the files that i want to delete is a ".txt" or ".doc" format files.
please any one help me

If you can see where it is, overwrite it with random data

Dude,

I think you want to delete a file completely from the hardisk if i am not wrong.

i hope you know the path of the file. here is the example

#include <stdlib.h>
void main()
{
system("del c:\\delme.txt") ;
}

Now you can pass any command you want to run (directly or as a string) to the system function.

can you please tell me how the code works?

#include <stdlib.h>
void main()
{
system("del c:\\delme.txt") ;
}

In the line, system("del c:\\delme.txt") ;, whether the del is the dos command that we use?

yes, the parameter to system() is as though you were typing at the Command Prompt (the DOS prompt as it was called), e.g. you can

	system("dir *.c");

to get a directory listing
