How to View Blocked File Types in SharePoint 2013

We have already explained the concept of “SharePoint document library” in one of our previous tutorials. In this tutorial, we will understand the concept of Blocked File Types in SharePoint along with the procedure to view them.


Viewing Blocked File Types :-

You can very easily view the complete listing of all blocked file types for your specific SharePoint environment by following steps given below –

  • Go to SharePoint Central Administration site
  • Navigate to Security group of links and locate the link to view Blocked file types
  • Click the link to open up a full list of blocked files


Security Risks with Blocked File Types :-

You can quite easily remove items from this Blocked files list so that users can upload files of that specific type to different SharePoint libraries created within a web application. However, you need to be careful enough to avoid allowing certain executables and file types that may lead to security risks or other related performance issues.


It is thus strongly recommended that you must speak with someone having expertise in managing security within your entire network before you proceed to removing a specific file type from this list. Typically, this Blocked file type list should never be modified unless a major business case demands for it.


Hopefully this tutorial explains the concept of Blocked File Types clearly.
