Question

I want to get the file names of all files that have a specific extension in a given folder (and recursively, its subfolders). That is, the file name (and extension), not th

Here's my solution (works on *nix systems):

#include 

bool FindAllFiles(std::string path, std::string type, std::vector &FileList){
  DIR *dir;
  struct dirent *ent;
  FileList.clear();

  if ((dir = opendir (path.c_str())) != NULL) {
    //Examine all files in this directory
    while ((ent = readdir (dir)) != NULL) {
      std::string filename = std::string(ent->d_name);
      if(filename.length() > 4){
        std::string ext = filename.substr(filename.size() - 3);
        if(ext == type){
          //store this file if it's correct type
          FileList.push_back(filename);
        }
      }
    }
    closedir (dir);
  } else {
    //Couldn't open dir
    std::cerr << "Could not open directory: " << path << "\n";
    return false;
  }
  return true;
}

Obviously change the desired extension to whatever you like. Also assumes a 3 character type.
