Deleting IE Cache

Deleting IE Cache

• jen0s

  Hi there,
  
  If you handle the execptions that get thrown when you can't delete a file, your code will proceed along it's merry way and basically the files that can't be deleted (i.e. those that threw exceptions) will be ignored.
  
  For example:
  
  

  System.IO.DirectoryInfo folder = new System.IO.DirectoryInfo(Environment.GetFolderPath(Environment.SpecialFolder.InternetCache));

  foreach(System.IO.FileInfo file in folder.GetFiles())
  {
      try
      {
          file.Delete();
      }
      catch (Exception ex)
      {
          MessageBox.Show("Unable to delete file: " + file.FullName + "\n\n" + ex.Message);
      }
  }

  foreach (System.IO.DirectoryInfo subfolder in folder.GetDirectories())
  {
      try
      {
          subfolder.Delete(true); //Delete all subfiles & subfolders
      }
      catch (Exception ex)
      {
          MessageBox.Show("Unable to delete folder: " + subfolder.FullName + "\n\n" + ex.Message);
      }
  }
  
  Hope that helps a bit, but sorry if it doesn't.
  
  PS. I managed to get code colouring by copying from the IDE into MS Word and then from MS Word into the forum's interface. I got this tip from another post somewhere on the MSDN forums but I don't remember where (props to whoever posted it though)

  I was able to delete all the temporary IE cache files. I used the following codes as shown below:

   

  =================================================================

  using System;< xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" />

  using System.Collections.Generic;

  using System.Text;

  using System.IO;

   

  namespace DeleteIECache

  {

      class Program

      {

          public void DeleteCache()

          {

              DirectoryInfo directory = new DirectoryInfo(Environment.GetFolderPath(Environment.SpecialFolder.InternetCache));

              CleanUp(directory);

          }

   

          private void CleanUp(DirectoryInfo directory)

          {

              Console.WriteLine("Deleting files under " + directory.FullName);

   

              FileInfo[] files = directory.GetFiles();

              foreach (FileInfo file in files)

              {

                  try

                  {

                      file.Delete();

                      Console.WriteLine(file.FullName + " Deleted successfully");

                  }

                  catch (Exception)

                  {

                      Console.WriteLine("Unable to delete :" + file.FullName);

                  }

              }

   

              DirectoryInfo[] subDirectories = directory.GetDirectories();

              foreach (DirectoryInfo subDirectory in subDirectories)

              {

                  CleanUp(subDirectory);

                  if (subDirectory.GetFiles().Length == 0)

                  {

                      subDirectory.Delete();  

                  }

              }

             

          }

         

          static void < xml:namespace prefix = st1 ns = "urn:schemas-microsoft-com:office:smarttags" />Main(string[] args)

          {

              Program p = new Program();

              p.DeleteCache();

          }

      }

  }

  =================================================================

  OK, before the first foreach loop put the following:
  
  System.IO.FileInfo[] x = folder.GetFiles();
  MessageBox.Show(x.Length.ToString());
  
  And after the last foreach loop put the following:
  
  System.IO.FileInfo[] y = folder.GetFiles();
  MessageBox.Show(y.Length.ToString());
  
  Tell us what the message boxes show....

  I don't really know. Seeing as I can't replicate your problem it makes it harder to help
  
  Oh, and this:
  
  4) Have another look at the temporary internet files location (may require refresh of directory contents). The files will be gone.
  
  Should be exit the directory (i.e. go up one level in the hierarchy) and then go back in the directory. Somehow doing a refresh of the contents doesn't work (for me anyway).
  
  Are message boxes only appearing for index.dat or are you getting then for other files in your temporary internet folder as well
  
  What other contents (apart from index.dat) appear in your temporary internet files folder

  I tried with this but it didn`t work :(
  
  

  using System;

  using System.Collections.Generic;

  using System.ComponentModel;

  using System.Data;

  using System.Drawing;

  using System.Text;

  using System.Windows.Forms;

  using System.IO;

  using Microsoft.Win32;

  namespace Pc_Cleaner

  {

  public partial class Form1 : Form

  {

  public Form1()

  {

  InitializeComponent();

  }

  #region IECache

  private void IECache()

  {

  DirectoryInfo directory = new DirectoryInfo(Environment.GetFolderPath(Environment.SpecialFolder.InternetCache));

  CleanUp(directory);

  }

  private void CleanUp(DirectoryInfo directory)

  {

  Console.WriteLine("Deleting files under " + directory.FullName);

  FileInfo[] files = directory.GetFiles();

  foreach (FileInfo file in files)

  {

  try

  {

  file.Delete();

  Console.WriteLine(file.FullName + " Deleted successfully");

  }

  catch (Exception)

  {

  Console.WriteLine("Unable to delete :" + file.FullName);

  }

  }

  DirectoryInfo[] subDirectories = directory.GetDirectories();

  foreach (DirectoryInfo subDirectory in subDirectories)

  {

  CleanUp(subDirectory);

  if (subDirectory.GetFiles().Length == 0)

  {

  subDirectory.Delete();

  }

  }

  }

  #endregion IECache

  private void pictureBox2_Click(object sender, EventArgs e)

  {

  Form1 p = new Form1();

  p.IECache();

  }

  }

  }

  Do u know what's happening
  
  

• LostGamer

  What can be

  It should work.

  Can you post the exception message.

  It is reading the temporary internet folder from the environment variable. XP maintains a separate profile for separate logged in user.

  To execute your application, use admin profile.

  The first box show 1, while in the second 0

  The code is meant to display a message box when it can't delete something but will otherwise progress and delete everything it can delete. That makes it different from the code you have right now as it will have unhandled exceptions and bomb out when it finds something it can't delete.
  
  I have tried this on my machine and it deletes everything it can in Temporary Internet Files (apart from things it can't delete....then it will display a message box).
  
  Here's something you can do to check (might be easier if you don't have a web browser open, but it doesn't matter)
  
  1) Go to your temporary internet files location as specified by Environment.SpecialFolder.InternetCache. This will generally be under C:\Documents And Settings\<Your User Name>\Local Settings\Temporary Internet Files
  
  2) Bung a few test files in there (copy from some other location if you have to)
  
  3) Run your code
  
  4) Have another look at the temporary internet files location (may require refresh of directory contents). The files will be gone.
