How to find all documents of a certain content type?

Question

I have an content type I would like to delete, but when I try I get an error message saying that it is still in use. Is there a way that I can find all documents that are still using that content type?

Answer 1

Here is the code to do this using Powershell:

$site = Get-SPSite("your-site-url");
foreach ($web in $site.AllWebs) {
   $ctype = $web.ContentTypes["Your Content Type"]
   $usages = [Microsoft.Sharepoint.SPContentTypeUsage]::GetUsages($ctype)
   foreach ($usage in $usages) {
      Write-Host $usage.Url
   }
}

Answer 2

You can use code to delete the content type or report an error stating where it is being used.

Please refer to this simliar question.

Answer 3

I needed to do this same thing today. Get a list of SPContentTypeUsage's that define where the items are being used. If the Check if the URL is to a list (such as a Pages library), then run an SPQuery to get those SPListItem's that match your content type. You'll need to iterate over them in a for loop to delete them.

SPContentType ct = site.RootWeb.ContentTypes["CustomContentType"];

IList<SPContentTypeUsage> usages = SPContentTypeUsage.GetUsages(ct);

foreach (SPContentTypeUsage usage in usages)
{

    if (usage.IsUrlToList)
    {
        SPList list = web.GetList(usage.Url);
        SPQuery query = new SPQuery();
        query.Query = string.Concat(
                        "<Where><Eq>",
                            "<FieldRef Name='ContentType'/>",
                            string.Format("<Value Type='Text'>{0}</Value>", ct.Name),
                        "</Eq></Where>");
        SPListItemCollection listItems = list.GetItems(query);
        for (int i = 0; i < listItems.Count; i++)
        {
            listItems[i].Delete();
        }
    }
}
