Body: As with previous versions of SharePoint, SharePoint 2010 will not index the contents of files larger than 16 MB. There are a couple of reasons for this such as network usage pulling large files across and the time it takes to break them apart. While the file itself isn't indexed, the metadata is. So you'll be able to find the location of a 17 MB or larger file by searching for its name, or its author, you won't be able to find it by searching for words that exist in it. With previous versions of SharePoint, the fix for this was to add a Registry key called " MaxDownloadSize " and put a number between 17 and 64 in it. That tells the search engine to ignore the 16 MB limit, and go ahead and index files all the way up to 64 MB in size. However, in SharePoint 2010 this has changed a bit. The indexer still doesn't download files larger than 16 MB, so that's the same. The way to fix it though is different now. Thanks to the invention of PowerShell we can do...
