解决方案，我发现的是我创建的文件夹移动到新的

 var uploadDir = './uploads/databses/temp/'; 

     var form = new formidable.IncomingForm({ 
     uploadDir=uploadDir,  
     keepExtensions: true 
     }); 
     form.on('progress', function(bytesReceived, bytesExpected) { 
     console.log(100 * bytesReceived/bytesExpected + '%'); 
     }); 
     form.parse(req)  
     .on('field', function(name, fields) { 
     var body = JSON.parse(fields); 

     uploadDir='./uploads/databses/'+body.nameOfFolder+'/'; 
     form.uploadDir=uploadDir; 
     }).on('file', function(name, files) { 
     //moving temp to new folder 
     mv('./uploads/databses/temp', form.uploadDir, {mkdirp: true}, 
     function(err) { 

     }); 
     res.end(util.inspect({ 
     files: files 
     })); 
     }) 
     .on('error', function(err) { 
     next(err); 
     }) 
     .on('end', function() { 
     res.end(); 
     });
