This list will apply not only to the uploading of documents, but also to extensions changes of documents once they are in a document library. So if you have .zip file in a document library and try to unzip that file into a document library and the .zip contains a .exe file then that document won't extract.

To configure blocked file types:

  1. Go to Sharepoint 3.0 Central Administration.
  2. Select Operations page.
  3. Select Blocked File Types under Security Configuration.
  4. Modify the list to include or exclude the file extensions required.
  5. Click OK to save and close.
