Error: File Path is Too Long

Question

i am trying to use the various file functions in C# like File.GetLastWriteTime, copy command on the file placed at the path greater than maximum allowed path on

Here's a solution for at least the copying portion of your request (thank you pinvoke.net):

[DllImport("kernel32.dll", CharSet = CharSet.Unicode)]
static extern bool CopyFile(string lpExistingFileName, string lpNewFileName, bool bFailIfExists);

And then to actually copy your file:

// Don't forget the '\\?\' for long paths
string reallyLongPath = @"\\?\d:\abc\bcd\cd\cdc\dc\..........";
string destination = @"C:\some\other\path\filename.txt";
CopyFile(reallyLongPath , destination, false);
