New and Mysterious File Folders Appearing on my Win 7 Computer

The folder in your original post has 32 random characters. MSE creates temp folders with 32 random characters too - but only when certain parts of MSE require updates (scanning engines vs. definitions). The folder should go away after the update(s) completes. Perhaps something has changed recently that is causing some of them to be left behind. Maybe the change was on Microsoft's side.

I first noticed the appearance of one of these folders just after a patch Tuesday update about 3 months ago so as you pointed out these empty files could very well be a result of recent changes in the way that MSE handles it's temp files.

Thank you very much for all of the time and effort that you have put into helping me to find the source of these folders that were being created on my Win 7 computer as well as it's external SSD drive. I want you to know that I genuinely appreciate all of the intricately detailed and very helpful information that you have so knowledgeably posted in response to my inquiry.

UsernameIssues- Thank you again for all of your help in tracking down the source of the mysterious folders which had been appearing on the internal and attached drive of my computer. The above documentation provides sufficient confirmation for me to know that the files were indeed being created by MSE as you had suggested all along.

Actually I have never seen more than one of these folders at a time. Originally there was one on the root of my C drive that remained there for several months. One day I decided to delete it (because I could) and a singular second file appeared on my attached drive which I became concerned about. As I mentioned before each time I would delete the file another one would appear a few days later, but there was never more than one file at a time on the drive. Thanks to your help and guidance I was finally able to identify the mysterious folder as being created by MSE which was a great relief to me.
