Newbie Concern

I'm cleaning my storage on my mac when I found an unknown folder in my user folder. I do not know where this came from, maybe from an app I downloaded and uninstalled months ago. The folder is named "UltData_Serialize"– an empty folder with zero bytes on disk for one item. As a user with a little knowledge of software, I would like to ask if it is OK to delete the said file. I'm worried that it might be an important file in my user folder (along with Applications, Download, Desktop, etc.)

It might be a dumb question, but I would greatly appreciate any help I could get. Thank you.
