MIME Types
By default IIS will block serving content for MIME types that are unknown (flac and mkv, for example). You can add additional MIME Types (and remove others), if you wish to adjust what is supported. It is best practice to create an entry for each additional type you want to add. If you find yourself in a pinch, however, you can add a wildcard mapping until you can sort out the proper individual entries.
Click on “MIME Types” under “Default Web Site”
Click on “Add”
Add the new MIME Type extension and type and then click “OK”. In the example below we are adding the wildcard MIME mapping
If you plan to use IFS, odrive’s file splitting technology, you will want to add these two MIME Types:
Extension: “.meta”
MIME Type: “application/octet-stream”
Extension: “.”
MIME Type: “application/octet-stream”
