beyond 256 character for directories?

[Dale]

Is there a way to extend the directory structure beyond
256?

The limit is for the sum of all directories and file name
not to exceed 256 characters? Right?

Thanks!

Call the Unicode version of CreateFile( ..) API [ CreateFileW() ] and
prepend "\\?\" to the path to extend the limit to nearly 32,000 wide
characters.

Note even for the long paths (< 32367 wide characters) the size of each
element of the directory/file cannot exceed MAX_PATH (260 wide characters).
In other words, you can have a path upto 32367 wide characters such as
\\??\C:\Dir1\Dir2\Dir3.... but the length of the "Dir1" cannot exceed 260
wide characters.
