C++ mass file transfer

1. Rough quantitative transfer

When you encounter a very large number of files that need to be transferred from one folder to another, especially quantitative ones, it is really tiring to do it manually.

string&   replace_all(string&   str, const  string&  old_value, const  string&  new_value)
{
    
    
	while (true)
	{
    
    
		string::size_type   pos(0);

		{
    
    
			str.replace(pos, old_value.length(), new_value);
		}
		else {
    
     break; }
	}
	return   str;
}
int main()
{
    
    
	string DATA_DIR = "C:\\Users\\wwy\\Desktop\\refSave";//原文件夹
	vector<string> files;
	//测试

	{
    
    
		/*vector<string> test;

			cout << des_name << endl;
			system(des_name);
		}
       
		
			
		


	}


	/*string src = string("D:\\NewForWwy\\workspaceForMine\\DATASET\\VOCofMine\\JPEGImages\\") + "NotVehicle_2" + ".jpg";
	string dst = string("D:\\NewForWwy\\workspaceForMine\\DATASET\\VOCofMine\\test") ;

			}
		} while (_findnext(hFile, &fileinfo) == 0);  //寻找下一个，成功返回0，否则-1
		_findclose(hFile);
	}
}

2. Transfer a large number of files to multiple folders quantitatively

Quantification is transferred to multiple folders like this, but the order is chaotic, the order is 1, 10, 11, 101...

//#include <iostream>
//using namespace std;
//
//int main()
//{
    
    
//	string folderPath = "C:\\Users\\大喵喵\\Desktop\\大气湍流\\turbulence_dataset\\algorithm_simulated_videos\\blur\\00";
//
//	string command;
//	command = "mkdir -p " + folderPath;
//	system(command.c_str());
//
//	return 0;
//}

3.opencv transfers a large number of files to multiple folders quantitatively and sequentially

① The opencv library is required
② The file name needs to be a pure number, for example: 1.jpg, 2.jpg…
