Move File Functions

On same drive

	string source_path;
	string dest_path;
	source_path = "/home/pi/file_oldname";
	dest_path = "/home/pi/file_newname";
	rename(source_path.c_str(), dest_path.c_str());

To an external drive

Moving between file systems is not possible with rename() 

	string source_path;
	string dest_path;
	source_path = "/home/pi/file_oldname";
	dest_path = "/home/pi/file_newname";
	ifstream ifstream1(source_path.c_str(), ios::in | ios::binary);
	ofstream ofstream1(dest_path.c_str(), ios::out | ios::binary);
	ofstream1 << ifstream1.rdbuf();
	remove(source_path.c_str());

Move Multiple Files Using A Command

#define DB_FILEIO_DIRECTORY_1	"/home/pi/myfolder1"
#define DB_FILEIO_DIRECTORY_2	"/home/pi/myfolder2"

	string CommandString;

	//Example command: "mv /path/sourcefolder/* /path/destinationfolder/"
	CommandString = "mv ";
	CommandString += DB_FILEIO_DIRECTORY_1;
	CommandString += "/*.txt ";	//Use this for all files: "/* "
	CommandString += DB_FILEIO_DIRECTORY_2;
	CommandString += "/";
	system(CommandString.c_str());
