my flash drive gave me an error message Excel cannot open file because file format or file extension not valid. I was able to recover all of my Excel documents and save to a new flash drive but am afraid that Stellar can now now access that data as well I assume that the programs uploads the data to somewhere? (their server maybe?) so that i could download it to my hard drive.
