				SH3D is the main file format of Sweet Home 3D, which stores a home designed with this software. It is a ZIP archive which may contain the following files:
- Home
 - The home, stored using Java Object Serialization.
 - Home.xml
 -  An XML representation of the same home, introduced in version 5.3. It is prioritized over 
Home, butHomeis still saved for backwards compatibility. - ContentDigests
 - A text file whose contents resemble MIME headers, introduced in version 4.4. It contains SHA-1 hashes for the images and 3D models used by the home.
 
1-indexed numbered directories and files may also exist in the archive, holding textures and 3D models used by the home when they are not built-in. These are in JPEG, MTL and OBJ format.
