Document
A Sandvox document is the file that a site is stored in on your computer. It contains all the information necessary to publish the site, such as the design, ordering of pages, text, etc.
As you work on a site, Sandvox automatically saves the entirety of it into a single document file. The exception to this is media files; You choose whether they are kept in the document or linked to. For information, please see the "Media" article.
When you come to publish a site, Sandvox takes the document and uses it to produce all the individual files that make up the published site, like this:
Sandvox Upgrades
When Sandvox is upgraded, changes are sometimes made to how the contents of Sandvox documents are stored. This means that if you open a site in a newer version of Sandvox, you may be prompted to upgrade the document.
If you accept, Sandvox will upgrade the document (the new version will only work with the updated version of Sandvox) and also save a copy of the old document just in case.
