11:49 AM Ruby Bug #7821: FileUtils.mkdir_p fails on Windows Unicode paths (\\?\UNC\) if dir already exists

This is actually due to a bug in File.directory?
~~~
File.directory?("\\\\?\\C:")
~~~
returns false. New bug for this? elovelan (Eric Loveland)

11:19 AM Ruby Bug #7822: Dir.mkdir can't handle long Windows Unicode paths (\\?\UNC\)

I would recommend that this bug be closed. However, I have not found any feature requests for better support of "\\\\?\\". Is it worth submitting one or would this be better handled with a gem? elovelan (Eric Loveland)

03:36 AM Ruby Bug #7822: Dir.mkdir can't handle long Windows Unicode paths (\\?\UNC\)

The linked article mentions that each component (individual folder in the path) can have a maximum of 255 characters.
The following works:
~~~
Dir.mkdir "\\\\?\\C:\\#{'t'*255}"
Dir.mkdir "\\\\?\\C:\\#{'t'*255}\\#{'t'*255}"
~~~
