My function is pretty much a standard search function... I've included it below.

In the function I have 1 line of code responsible for weeding out Repart NTFS points.

if (attributes.ToString().IndexOf("ReparsePoint") == -1)

The problem is now I am getting an error Access to the path 'c:\System Volume Information' is denied.

I debugged the code and the only attibutes at run time for this directory are :

System.IO.FileAttributes.Hidden | System.IO.FileAttributes.System | System.IO.FileAttributes.Directory

I'm executing this code on a windows 2008 server machine, any ideas what I can do to cure this failing?

public void DirSearch(string sDir)
        {

                foreach (string d in Directory.GetDirectories(sDir))
                {
                    DirectoryInfo dInfo = new DirectoryInfo(d);
                    FileAttributes  attributes = dInfo.Attributes;
                    if (attributes.ToString().IndexOf("ReparsePoint") == -1)
                    {
                        foreach (string f in Directory.GetFiles(d, searchString))
                        {
                            //lstFilesFound.Items.Add(f);
                            ListViewItem lvi;
                            ListViewItem.ListViewSubItem lvsi;
                            lvi = new ListViewItem();
                            lvi.Text = f;
                            lvi.ImageIndex = 1;
                            lvi.Tag = "tag";
                            lvsi = new ListViewItem.ListViewSubItem();
                            lvsi.Text = "sub bugger";
                            lvi.SubItems.Add(lvsi);

                            lvsi = new ListViewItem.ListViewSubItem();
                            lvsi.Text = d;//"C:\\Users\\Administrator\\Downloads\\MediaMonkey.GOLD.EDITION.v.3.0.2.1134.[Darkside].[Demonoid].[Grim.Reaper]";
                            lvi.SubItems.Add(lvsi);

                            listView1.Items.Add(lvi);
                        }
                        DirSearch(d);
                    }

                }




        }

I'm not sure what the answer to the question is, but please change your attribute check to use proper bitwise operations!

if (attributes.ToString().IndexOf("ReparsePoint") == -1)

... is much more correctly written as ...

if ((attributes & FileAttributes.ReparsePoint) == 0)

thats a great tip, thanks for sharing

Nobody has permission to access System Volume Information except the SYSTEM account. So either change the permissions on the directory. Or much, much better catch the exception and go on.

Stephen, thanks for your answer - it seems I am getting some other interesting access denied error messages. I will need to fully research why. Windows 2003 never gave such issues.

Perhaps this article could help you (they explain how to get access to this folder):

The desperate solution is try - catch.
