Define file formats

You can add new types to the list of MIME types supported by IXIA CCMS.

Multipurpose Internet Mail Extension (MIME) types are two-part identifiers for file formats on the Internet. The mimetype.xml file defines the MIME types supported by CCMS, along with their expected file extensions. For example, if your Content Store includes .jpg image files, this file defines the extension so that the jpg images within your documents can be properly rendered.

If you also intend to store the image source files in the Content Store, define their MIME types in the mimetype.xml file. For example, if you are importing files such as Adobe Illustrator, edit the mimetypes.xml file to include the application/illustrator MIME type. If the source file's MIME type is not defined, the extension will be converted to a .bin extension when it is imported into the Content Store.

Important: Make configuration changes in a test environment and confirm they work before copying them to a production environment. For dedicated SaaS deployments, test the changes and then ask IXIA CCMS Customer Support to copy the changes to your production environment.

In the TEXTML Administration perspective, connect to your server.
Locate the mimetype.xml file in the repository's /system/conf collection.
Check out the file and open it for editing.
Enter a new <mimetype> element.
For example:
```
<mimetype type="image/jpg">
```
Note: The value of the type attribute must be one of the MIME media types defined by the Internet Assigned Numbers Authority (https://www.iana.org/).
Create an <extensions> element and, under it, a <defaultextension> element to specify the extension used when files are exported from the system.
For example:
```
<extensions>
   <defaultextension>jpg</defaultextension>
</extensions>
```

Optionally, use the <extension> element to define alternative file extensions.

For example:

<mimetype type="image/jpeg">
   <extensions>
      <defaultextension>jpg</defaultextension>
      <extension>jpeg</extension>
   </extensions>
</mimetype>

Save, close, and check in the file.
Inform users of the changes.
The changes will be applied automatically once users close and then reopen their IXIA CCMS Desktop. Users can also apply the changes without restarting their CCMS Desktop by clicking IXIA CCMS > Synchronize Configuration.
