Answer 1

Hi Rajashekhar, I have written below function which deletes contents of temp, recent and prefetch folders (skipping the items which cannot be deleted). Just call the function CleanTemporaryFolders function.

private void CleanTemporaryFolders()
{
    String tempFolder = Environment.ExpandEnvironmentVariables("%TEMP%");
    String recent = Environment.ExpandEnvironmentVariables("%USERPROFILE%") + "\\Recent";
    String prefetch = Environment.ExpandEnvironmentVariables("%SYSTEMROOT%") + "\\Prefetch";
    EmptyFolderContents(tempFolder);
    EmptyFolderContents(recent);
    EmptyFolderContents(prefetch);
}
        
private void EmptyFolderContents(string folderName)
{
    foreach (var folder in Directory.GetDirectories(folderName))
    {
        try
        {
            Directory.Delete(folder, true);
        }
        catch (Exception excep)
        {
            System.Diagnostics.Debug.WriteLine(excep);
        }
    }
    foreach (var file in Directory.GetFiles(folderName))
    {
        try
        {
            File.Delete(file);
        }
        catch (Exception excep)
        {
            System.Diagnostics.Debug.WriteLine(excep);
        }
    }
}

I hope this helps.
