The SiteAssets folder in the turnkey application is a folder that declares extra mime types.

The extra mime types makes this folder ideal for hosting content that is not usually downloadable by IIS or IIS express.

Use this location for report templates of OpenDocument format - like odt, ods and odp.

The following types are added - if you need others you can let us know and we will include in next build:

<mimeMap fileExtension=".mp4" mimeType="video/mp4" />
<mimeMap fileExtension=".odt" mimeType="application/vnd.oasis.opendocument.text " />
<mimeMap fileExtension=".ods" mimeType="application/vnd.oasis.opendocument.spreadsheet" />
<mimeMap fileExtension=".odp" mimeType="application/vnd.oasis.opendocument.presentation" />
<mimeMap fileExtension=".xps" mimeType="application/octet-stream" />
<mimeMap fileExtension=".eot" mimeType="application/vnd.ms-fontobject" />
<mimeMap fileExtension=".ttf" mimeType="application/octet-stream" />
<mimeMap fileExtension=".svg" mimeType="image/svg+xml" />

Some types may be part of global already depending on environment - in order to not conflict with global we do <remove fileExtension=".odt" /> before adding .odt
