info
Provides package information, including the version number, ContentID, ProductID, GameOS version, and encryption key IDs.Arguments
compare
Compares a base package with an updated package and reports the differences, including update size and changed segments.Arguments
Options
PackageUtil produces an HTML report of the content downloaded when updating from the base package to the updated package. The report includes an estimated update download size.
Both packages must use
/lk encryption or the default encryption mode. Don’t use /l, because the comparison results aren’t accurate for packages that use a unique content license.
license

/l) - only for submission to Partner Center. - Test signed (
/lt) - sideload enabled and insecurely encrypted.
Currently,
packageutil license reports /lk-signed packages as /l-signed packages.Arguments

JSON output for middleware and custom tooling
When you runcompare, PackageUtil creates a JSON companion file with the HTML report. Middleware, engines, and custom tools can use this file to inspect the package layout, locate files in the package binary, verify alignment, or extract structural information without unpacking the package.
The fileinfo command also produces structured output suitable for machine processing.
The JSON output uses abbreviated field names to keep the file size small.
