from the link you gave me
first paragraph
yes... and the second paragraph
The Windows API has many functions that also have Unicode versions to permit an extended-length path for a maximum total path length of 32,767 characters. This type of path is composed of components separated by backslashes, each up to the value returned in the lpMaximumComponentLength parameter of the GetVolumeInformation function (this value is commonly 255 characters). To specify an extended-length path, use the "\\?\" prefix. For example, "\\?\D:\<very long path>". (The characters < > are used here for visual clarity and cannot be part of a valid path string.)
and a few lines below that..
The shell and the file system have different requirements. It is possible to create a path with the Windows API that the shell user interface might not be able to interpret properly.
For this reason the support for this should be an option in settings...
Explorer in Windows 7 64bit has no problem entering folder-structures that have many hundreds(only tested upto 1020chars, cause my filemanager seem to not support longer paths) of total chars, max length per single directory is 255chars it seems... Explorer in Windows XP 32bit complain about not finding the files/folders....
I could not have any of the Explorer versions create such a folder-structure though...
The structure I tested with was:
