public void DeleteFileFromFolder(string StrFilename)
{

    string strPhysicalFolder = Server.MapPath("..\\");

    string strFileFullPath = strPhysicalFolder + StrFilename;

    if (IO.File.Exists(strFileFullPath)) {
        IO.File.Delete(strFileFullPath);
    }

}

Answer 2

In order to delete a file you must ensure that the account has sufficient permissions. In general ASP.NET applications run under limited permission account such as Network Service . For example if your application runs under IIS 6 you could go to the Administration Console and set a custom account in the application pool properties:

You need to ensure that the account is member of the IIS_WPG group.

Make sure the ASP user has permissions to this folder. By default this user is not given access to much of the harddrive..
