Renamed folder still shows up in Explorer - How to clear Windows Folder
Cache?

I have renamed "Downloads" folder to "OldDownloads" from my D: Drive, and
when I issue dir command in command line, I see that Downloads folder is
renamed to OldDownloads and when I try to issue command "cd downloads" I
get an error.
However, when I open Windows Explorer, I still see Downloads folder and I
dont see OldDownloads folder.
When I double click on any file inside "Downloads" folder, I get an error
saying file does not exist. I wrote a custom c# command line program to
access file from "OldDownloads" folder, I can access it fine.
It seems, folder is successfully renamed, but however Windows Explorer
still remembers old folder name and gives wrong path to programs.
