char Statistic_File[MAX_PATH]; // Name of the file
...

När namnet ska fastställas:
// Set statistic file name with the extension of ".TXT"
sprintf(Statistic_File   , _argv[0]);
sprintf(strrchr(Statistic_File   ,'.') + 1,"txt");
Nu innehåller 'Statistic_File' samma path och namn som programmet heter men med ".TXT" som extension mot ".EXE" för programmet
...

När data ska sparas:
DWORD Did_Write;
HANDLE Stat_File = CreateFile(Statistic_File,GENERIC_WRITE,FILE_SHARE_READ,0,OPEN_EXISTING,FILE_ATTRIBUTE_NORMAL,0);
if(Stat_File != INVALID_HANDLE_VALUE)
  {
//  SetFilePointer(Stat_File,0,0,FILE_END); // Move to the end of the file in order to append, ONLY USED WHEN APPENDING TO A FILE!!!!
  WriteFile(Stat_File,&Buffer,strlen(Buffer),&Did_Write,0);
  CloseHandle(Stat_File);
