C # - How to delete temporary Internet files

Question

I want to completely clear the folder of temporary Internet files. The location of the folder, for example C:\Users\Username\AppData\Local\Microsoft\Windows\Temporary Internet Files, depends on the version of Windows, so it must be dynamic.

Answer 1

use this way: Environment.SpecialFolder.InternetCache

string path = Environment.GetFolderPath(Environment.SpecialFolder.InternetCache)
//for deleting files
System.IO.DirectoryInfo di = new DirectoryInfo(path);
foreach (FileInfo file in di.GetFiles())
{
    file.Delete(); 
}
foreach (DirectoryInfo dir in di.GetDirectories())
{
    dir.Delete(true); //delete subdirectories and files
}

Answer 2

You may also need to kill the Internet Explore process and change the attributes of the directory, and don’t think that this will work for Index.dat files, as MS continues to change the rules.
