Retrieving info on files with a long name using .NETI had previously written a program to set the attributes of all files in a
folder. The program uses the Windows API functions FindFirstFile and FindFindNextFile to process the files in a specified folder and its sub-folders. By specify the prefix “\\?\UNC\†or “\\?\†files or folders with names longer than 260 characters are processed. I have now written a VB.NET 2003 equivalent using.NET Framework version 1.1. The program uses the Directory class methods GetDirectories and GetFiles, and the FileInfo and FileAttributes classes to do exactly the same thing. However it appears that these .NET Framework classes do not accept the long file name prefix in the path so the program cannot set the attributes of files or folders with long names. Is there any other method for returning FileInfo objects for files with long names other than calling the FindFirstFile and FindFindNextFile from the VB.NET program -- Ade Hi Ade,
Welcome to MSDN Newsgroup! .Net Framework don't support name prefix. As a workaround for this issue, we should modify this file/directory name manually at first and then pass modified name in the relevant method. Just like: Convert "\\?\c:\<path>" to "c:\<path>" Convert "\\?\UNC\<server>\<share>\". to "\\<server>\<share>\". The following article is about how to operate files using c#. I hope it's useful for you: Title: File Information using C# URL: http://www.codeproject.com/csharp/file_operations.asp I hope the above information is helpful for you. Thanks and have a nice day!

Thanks for your reply. That is disappointing as I am trying to encourage the use of .NET by converting old programs to .NET when we get requests to modify them. I assume this apply to Framework 2.0 as well. I am going to have to carry on using the old Windows API program as the program processes the files automatically via a scheduled task that runs overnight. The user will not think that having to manually modify long file names is a step forward.
