*censored*, they always hook me on something....
There is another way to create "con" directory.
At Command Prompt, type:
mkdir \\.\c:\con
I just tried it, and it works.
Interestingly, you can't remove that directory by just deleting it through Windows Explorer. Delete command returns an error: directory doesn't exist on C drive anymore. Strangely enough, I can move files to, and from it.
To remove "con" directory, at Command Prompt, type in:
rmdir \\.\c:\con
