Problem: When I try to upload files using postman, files get uploaded to the destination folder. But I want to upload files in destination folder in controller function after performing some operation
How can I store files in the destination folder?
In controller function when I console.log(req.files) I get: 
What did I do:
I use multer.memoryStorage() to store files in memory not in destination folder.
And In controller function I get files in req.files
What I want to do: save each files to destination folder (upload/files)
