I am taking a day or two off from my world editor to build a simple (actually, rebuild) temporary file remover, which will delete all the files in "Windows\TEMP" and in any of it's subfolders, as well as the actual subfolder. I have two questions about this though. When FindFirstFile or FindNextFile return, they only return the file or directory name, and I need the full drive and path to delete files and subfolders. Second, can a function call on itself? The way I plan on doing it is this (this is my actual code so far):

void remove(char place[512])
	{
	WIN32_FIND_DATA fd;

	fn = FindFirstFile(place, &fd);

	if(fd.dwFileAttributes == FILE_ATTRIBUTE_DIRECTORY)
		{
		/*
		First get the full path and directory name
		Now call remove() with that info
		Once it returns, you can delete the empty folder!
		*/
		}
	else
		//Just delete the file, if not a dir

	//Code in a loop with FindNextFile here!
	return;
	}

void clean(HWND cwnd)
	{
	if(strstr(paths[0], "Not used.") == NULL)
		remove(paths[0]);
	return;
	}

Can somebody please help me out with this? I appreciate it.

Ok. There is nothing wrong with functions calling themselves.

int factorial(int n)
{
  return ((n <= 0) ? 1 : n * factorial(n - 1)); 
};

Like this one. It is often more effective when functions call themselves then using cycles.
Though, every calling of a function costs some time, of course. Using cycles is faster.

Very well, I think with our 1GHz proccessors it doesn't matter at all. ;o)

Reunion

So you're talking about recursive function call. This is very handy in a case like deleting subfolders and contents. Here's my code that finds all .mp3 files and changes their attributes. I think there's some bug in it but you get the picture.

void searchloop(void) {
long res;
struct _finddata_t fileinfo;

res = _findfirst("*.*", &fileinfo);

while(1) {
if((strcmp(fileinfo.name, ".") != 0)&&(strcmp(fileinfo.name, "..") != 0))
if(_chdir(fileinfo.name) == 0) {
searchloop();
} else {
if(!strcmp(fileinfo.name, ".mp3")) {
SetFileAttributes(fileinfo.name, FILE_ATTRIBUTE_NORMAL);
}
}
if(_findnext(res, &fileinfo) < 0)
break;
}
_chdir("..");
}
