Programatically filtering SharePoint 2010 lists that may have files by base templates

Hope this will find an answer and will be useful for somebody else looking for the same solution.

I have identified the following list types and their respective BaseTemplates (see text in quotes) as those type of lists where users can upload files to:

1. Documents Library: "DocumentLibrary"


2. Asset Library: "851"


3. Report Library: "433"


4. Picture Library: "109"

My code reflects the definitions above:

$siteURL = "http://yoursite"
$site = new-object Microsoft.Sharepoint.SPSite($siteURL)
$webApp = $site.WebApplication
$allSites = $webApp.Sites
foreach ($site in $allSites) 
{
    $allWebs = $site.AllWebs
    foreach ($web in $allWebs) 
    {
        $lists = $web.Lists
        foreach($list in $lists)
        {
            #Getting the base template of each list found
            $ListBaseTemplate = $list.BaseTemplate

            #Filtering lists where users can upload files to
            if($ListBaseTemplate = "DocumentLibrary" -or $ListBaseTemplate = "851" -or $ListBaseTemplate = "433" -or $ListBaseTemplate = "109")
            {
                #I think I am not missing any uploaded file to our SharePoint
                foreach ($item in $list.items)
                {
                    #Getting file properties
                }
            }
        }
    }
}

My question is if this code could miss files uploaded to SharePoint 2010
