NTFS supports pathes up to 32767 unicode characters.
Microsoft Windows uses the following types of paths:
local file system (LFS), such as C:\File,
uniform naming convention (UNC), such as \\Server\Volume\File,
Long UNC or UNCW, such as \\?\C:\File or \\?\UNC\Server\Volume\File.
I have to say that the windows standard tools like the explorer do not work with such long pathes.
And most programs do not (yet) support these also. Therefore this is a special issue.
Peter has provided a first implementation of a Large-Path Library. It substitutes the PB-commands with Commands that will enable you to utilize that large pathes.
