The filename or extension is too long.

Cleaning up after a Windows 8 restore and had problems deleting some files. According to KB320081 one possible way was to “Use an auto-generated 8.3 name to access the file”. After some searching I found what this means thanks to this post (it annoys me to no end that lot’s of posts just copy and pasted the details in the KB320081 page and don’t explain how to use the 8.3 name for deleting stuff). So the 8.3 name is the first 6 letters of the file name appended with a ~1 with any similar files will have an incremented number (~2, ~3, etc) as shown below.

1. My Chicagotech A.doc => MYchic~1.DOC
2. My Chicagotech B.doc => MYchic~2.DOC

I used this to help delete some files but even that didn’t manage to delete some files. In the end a “del name*” helped
