If you use MS Windows you can use GetFileAttributes.

Another option is :

#include <stdio.h>
#include <iostream>
#include "KLibIncUse.h"

using namespace std;

const _fsize_t  _1K = 1 * 1024;


void FuncFndSizeLessThan1k(const KStr & strDir, const _finddata_t & fi, void * pvParam);


int main(int argc, char * argv[])
{
   KDirTraverser dirTrv;
   dirTrv.SetFileSpec("*.*");
   dirTrv.SetFileExecInfoFunc(FuncFndSizeLessThan1k, NULL);
   dirTrv.SetRecurtSubDirs(true);         // process sub directories as well
   dirTrv.Execute();

   return 0;
}


void FuncFndSizeLessThan1k(const KStr & strDir, const _finddata_t & fi, void * pvParam)
{
   if (fi.size < _1K)
   {
      cout << "dir [" << strDir.sz() << "],  fname [" << fi.name << "]" << endl;
   }
}

This solution uses Kahless_9 framework which you can download from: www.shankodev.com download page. The Linux version doesn't allow function pointer passing _finddata_t as this is windows specific, but can still use same code with function pointer to string based filename and then use KFileIO::FileSize on respective file.
