Rules at a Glance

• path can be either an absolute path (a complete path from the root directory to the target directory) or a relative path (starting from the current directory to the target directory).

• path can be either a path on the local system, the path of a mapped network drive, or a UNC path. For example, the code:

   Directory.GetDirectoryRoot("\Pentium\C\AFolder") 

  returns \\Pentium\C , and if the folder \\Pentium\C\AFolder maps to the network drive Z, then:

   Directory.GetDirectoryRoot("Z:\temp") 

  returns Z:\ .

• path cannot contain wildcard characters .
