Windows 7 .ci, .wid, .dir, file deletion

[KJW]

Hi, All. I'm trying to free up space so I can update from Windows 7 Home Premium to Windows 10. I have installed DupeGuru and have been able to get rid of a bunch of stuff. However, I have literally thousands of dupe .ci, .wid, and .dir files. Is there any way to delete them? If so, I need directions a 5 year old can follow and would appreciate any help you can give.

Thanks!

KJ

Does anyone have suggestions I can try?
