Indexing Large Files in SharePoint 2010


Like it’s predecessor, SharePoint 2010 also doesn’t index files larger than 16 MB by default. This is because the search service application property ‘MaxDownloadSize’ is set to 16 MB by default. We can change this by running the following PowerShell commands and restarting search service.

$dSize = Get-SPEnterpriseSearchServiceApplication;
$dSize.SetProperty("MaxDownloadSize", 32);
$dSize.Update();

The above commands will increase the max size of files that SharePoint can index to 32 MB from 16 MB (default).

To restart search service, run the following command on the indexing server.


Restart-Service osearch14;
