[~,ListofImages]=dos('dir   /b /s *.jpg');
FileIndexes=[0,strfind(ListofModels,'.jpg')+4];
RegExFileName = '[0-9]+_new'; 
for loop1 = 1:length(FileIndexes)-1;
    FileFullName_Old=ListofModels(FileIndexes(loop1)+1:FileIndexes(loop1+1)-1);
    [FilePath,FileName,~]=fileparts(FileFullName_Old);
    [~,StartIdx]=regexpi(FileName, RegExFileName , 'match');
    FileIndx = FileName(1:end-4);
    FileIndx = str2num(FileIndx);
    NewFileName = ['tour',num2str(FileIndx),'_pictures'];
