You can save your bundle at any point using the Save button. This will save any changes made to your current bundle project. The bundle project file will be stored with the file extension ".zbx " and this file contains all the instructions and data that Zylpha Bundling requires to produce your final bundle. If you save and then reopen a bundle you will see that the same sections, documents and any other settings are preserved within the bundle.
If this is your first time clicking Save you will instead be prompted to Save a Copy. You will be able to either save the bundle to a recent location or browse using the file explorer to save in a location on your PC, or directly to a document or case management system.
