Question

How to get the File Directory of a file (C:\myfolder\subfoler\mydoc.pdf). I also want to add the size of the subfolders, and finally the main folder size. This is for a .NET CLR that I need to integrate with SQL Server 2005 for a SSRS report.

You can use GetDirectoryName, to get only the directory path of the file:

using System.IO; string directoryName = Path.GetDirectoryName(@'C:\myfolder\subfolder\mydoc.pdf'); // directoryName now contains 'C:\myfolder\subfolder' 

For calculating the directory and subdirectory size, you can do something like this:

public static long DirSize(DirectoryInfo d)  {         long Size = 0;         // Add file sizes.     FileInfo[] fis = d.GetFiles();     foreach (FileInfo fi in fis)      {               Size += fi.Length;         }     // Add subdirectory sizes.     DirectoryInfo[] dis = d.GetDirectories();     foreach (DirectoryInfo di in dis)      {         Size += DirSize(di);        }     return(Size);   }
