Global options
| Option | Description |
|---|---|
/v |
Enables verbose output to the console. |

info
Provides information about a package, including version number, ContentID, ProductID, GameOS version, and encryption key IDs.
packageutil2 info <packagefile>
Arguments
| Argument | Description |
|---|---|
<packagefile> |
Specifies the package file to examine. |
compare
Compares a base package with an updated package and reports the differences, including update size and changed segments.
packageutil2 compare <basepackagefile> <updatedpackagefile> [options]
Arguments
| Argument | Description |

<basepackagefile> |
Specifies the base package for the update comparison. |
<updatedpackagefile> |
Specifies the updated package for the update comparison. |
Options
| Option | Description |
|---|---|
/quiet |
Only print the summary information. |
/out <out> |
Specifies the output directory for comparison reports. |
license
Displays information about the signing key used on a package. Optionally checks whether an EKB file matches the package.
packageutil2 license <packagefile> [<ekbfile>]
Arguments
| Argument | Description |
|---|---|
<packagefile> |
Specifies the package file to examine. |
<ekbfile> |
Optionally specifies an EKB file to check against the package to see if they match. |
osinfo
Provides information about a game OS, including GUID and four-part version number.
packageutil2 osinfo <gameos>
Arguments
| Argument | Description |
|---|---|
<gameos> |
Specifies the game OS file to examine. |
chunkinfo
Provides information about the chunks in a package, including chunk ID, chunk size, and Intelligent Delivery specifiers.
packageutil2 chunkinfo <packagefile>
Arguments
| Argument | Description |
|---|---|
<packagefile> |
Specifies the package file to examine. |
fileinfo
Provides information about files in a package, including file names, sizes, and segment details.
packageutil2 fileinfo <packagefile> [options]
Arguments
| Argument | Description |
|---|---|
<packagefile> |
Specifies the package file to examine. |
extract
Extracts one or more files from a package to a specified output directory.
Note
Extract is only supported for MSIXVC2 packages.
Note
Extract can only extract from unencrypted packages. It can't extract from a package file on the Xbox CDN, for example.
packageutil2 extract /package <packagefile> /out <outputdir> [options]
Options
| Option | Description |
|---|---|
/package <package> |
Specifies the MSIXVC or MSIXVC2 package file. |
/file <file> |
Specifies a specific file to extract. If omitted, all files are extracted. |
/out <out> |
(Required) Specifies the directory to extract content to. |
Sample usage:
packageutil2 extract /package MyGame.msixvc /out extracted_files
Differences from packageutil
packageutil2 is the successor to packageutil and includes the following improvements:
| Feature | packageutil | packageutil2 |
|---|---|---|
| MSIXVC2 format | Not supported | Fully supported |
| Extract files | Not supported | Built-in extract command |
| File information | Not supported | Built-in fileinfo command |
| Comparison reports | Detailed reports output to the package directory | Detailed reports with configurable output location via /out |
Note
For MSIXVC (v1) packages, both packageutil and packageutil2 are supported. For MSIXVC2 packages, packageutil2 is required.
JSON output for middleware and custom tooling
When you run compare, packageutil2 creates a JSON companion file along with the HTML report. Middleware, engines, and custom tools can use this JSON file to programmatically inspect the package layout. For example, they can use it to locate files within the package binary, verify alignment, or extract structural information without fully unpacking the package.
The fileinfo command also produces structured output that's suitable for machine consumption.
The JSON output uses abbreviated field names to keep the file size small. The following table lists the key abbreviations.
| Abbreviated name | Full name | Description |
|---|---|---|
O |
Offset | The byte offset of a data segment within the package file. |
L |
Length | The length in bytes of a data segment. |
Typical integration scenario: An engine or tool reads the JSON output to build an index of file locations within the package. By using this index, the tool can directly read or validate specific assets without extracting the full package. This scenario is the primary use case for middleware that needs to assess package contents as part of a build or validation pipeline.
