Clean Database Function

The Clean Database function removes built-in CAB files from an MSI and reduces file size. It is useful after repeated builds or when temporary embedded data accumulates inside the database.

What it does​

  • Removes internal CAB data while preserving tables and relationships.
  • Reduces MSI size by cleaning outdated embedded cabinet content.
  • Leaves the database ready for a new Build CAB Files operation.

How to use it​

  1. Open your MSI in Master Packager.
  2. Go to the Build menu.
  3. Select Clean Database and confirm.
  4. Save the MSI after the embedded CAB data is removed.

When to use it​

Use this function when you need to:

  • Reduce MSI size after multiple build operations.
  • Rebuild CAB files with updated application files.
  • Share or archive a lighter version of the MSI without embedded installation data.
tip

Use Clean Database before finalizing or distributing a package so it contains only current data.
