Here is snapshot of my external drive. I never store any files directly in its root folder yet I have bunch of files eula.###.txt and others for example install.exe and similar files. How did they get there?

More important there are a number folders with numeric names. These are all zero bytes folders and has nothing inside them. What does this mean and how did it get there?

Note: I have masked my own files with boxes.

    They are Windows Updates, which has a habit, of using the largest disk available to store the files. Which updates other than VC++ in the case of the folder you have provided, is more difficult to identify. Folders can be deleted if you don’t care about removing the updates.

These are leftover files from installations of Microsoft Visual C++ Redistributable for Visual Studio. I had them too. You can safely delete them.


  • You beat me to it, so +1. It doesn't explain the empty folders though, but from doing some quick Googling they are safe to delete. Sep 21, 2018 at 15:29
  • Yes, apparently the empty folders are temporary folders for Windows Updates, with some saying they're the .NET Framework.
