It’s not a real problem. NTFS support filenames up to 32K (32,767 wide characters). You need only use correct API and correct syntax of filenames. The base rule is: the filename should start with '\\?\' (see http://msdn.microsoft.com/en-us/library/aa365247(v=VS.85).aspx) like \\?\C:\Temp. The same syntax you can use with UNC: \\?\UNC\Server\share\Path. Important to understand that you can use only a small subset of API function. For example look at MSDN description of functions
CreateFile
CreateDirectory
MoveFile
and so on
you will find text like :
In the ANSI version of this function,
the name is limited to MAX_PATH
characters. To extend this limit to
32,767 wide characters, call the
Unicode version of the function and
prepend “\?\” to the path. For more
information, see Naming a File.
This functions you can safe use. If you have a file handle from CreateFile you can use all other functions used hFile (ReadFile, WriteFile etc.) without any restriction.
If you write a program like virus scanner or backup software or some good software running on a server you should write your program so, that all file operations support filenames up to 32K characters and not MAX_PATH characters.
