   • req.files.foo.mv: A function to move the file elsewhere on your server
   • req.files.foo.mimetype: The mimetype of your file
   • req.files.foo.data: A buffer representation of your file, returns empty buffer in case useTempFiles option was set to true.
   • req.files.foo.tempFilePath: A path to the temporary file in case useTempFiles option was set to true.
   • req.files.foo.truncated: A boolean that represents if the file is over the size limit
   • req.files.foo.size: Uploaded size in bytes
   • req.files.foo.md5: MD5 checksum of the uploaded file
