==Supported formats of model files==
Analytica supports two formats for saving models — the default format and an XML format. Both formats are text files, and are fairly easy to read. You can view and edit them in standard text editors and word processors. (See examples below.)

Analytica normally saves a new model in the default format. You can change to the XML format in by checking '''Save in XML Format''' in the '''Save as''' dialog when you first select '''Save''' from the [[File menu]], or whenever you select '''Save as'''. It remembers and reuses the format you select in future sessions.

==Sample default file format==
 
The default format lists each object with each attribute on a separate line. The first line gives its class and identifier. Subsequent lines give each attribute name, followed by “:” followed by the attribute value. Here is part of a sample model file in the default format:
