I try to work with DirectoryInfo, FileInfo with very long path.

  • I try use \\?\c:\long path (i got illegal caracter with fileInfo and DirectoryInfo)
  • I try use file://c:/long path (i got uri not supported)

Can i use ~ in a path or something else.

I read this post but i would like to use another way that call a API. Is it any other solutions ?

There is an article from microsoft for use \\? in file path link text

The question is how can i work with very long path, and DirectoryInfo, and FileInfo for path who are more longer that 256 char
