#2725 Warning when extracting CAB files: "There are some data after the end of the payload data"

[Don]

Hi Igor,

I am experiencing an issue when extracting .cab files using 7-Zip.

My Environment:

• 7-Zip Version: 26.05
• OS: Windows 10

The extraction completes, but it shows 1 error/warning at the end. The specific warning message is:
"Warnings: There are some data after the end of the payload data"

How to reproduce the issue:

1. Download a driver update archive (.cab) from the official Microsoft Update Catalog.
2. The specific file I am using is an Intel Corporation Display driver.
3. Extract the downloaded .cab file using 7-Zip, and the warning appears at the 100% mark.

I have attached a screenshot of the extraction window showing the exact warning.

Could you please look into this? Let me know if you need any further details.

Thank you for your amazing work on 7-Zip!

Best regards,

Yes, there is certificate data sometimes after cab file. 7-Zip doesn't read it because certificate is not part of cab file.
