The C language implements traversing all files in a folder

The C language implements traversing all files in a single folder

Recently, I have learned the basic knowledge of C language. There is one requirement that I need to traverse the files in the folder, which is very good for this kind of implementation. Then I made a code to traverse all the files and made the following records:

Implementation code:

#include <stdio.h>
#include <io.h>
int main (void)
{
  _finddata_t fileDir;


  long lfDir;


  if((lfDir = _findfirst(dir,&fileDir))==-1l)
    printf("No file is found\n");
  else{
    printf("file list:\n");
    do{
      printf("%s\n",fileDir.name);
    }while( _findnext( lfDir, &fileDir ) == 0 );
  }
  _findclose(lfDir);


  return 0;
}
