So If you want to deploy your Multimedia (Images\files) to File System. It is controlled by your Deployer Configuration (cd_storage_conf.xml). Please find the cd_storage_conf.xml file in your Deployer Application and set the Binaries to be deployed on to the Filesystem in it.
To do so, you need to de the following:
add a storage element for Filesystem as a child of storages element.
<Storages>
<Storage Type="filesystem" Class="com.tridion.storage.filesystem.FSDAOFactory" Id="storageFS" defaultFilesystem="false">
<Root Path="C:\myFsLocation" />
</Storage>
</Storages>
and use it to configure you binary item type to be deployed to filesystem as below:
<ItemTypes defaultStorageId="{defaultStorageId}" cached="false">
<Item typeMapping="Binary" storageId="storageFS" cached="false"/>
</ItemTypes>
