dumpsis [-l[-y]][-d directory] filename.sis

The following table lists the arguments to be specified with DumpSISTool.

Arguments Description

-d directory

Specifies the directory to which the files are extracted. The directory is created if it does not exist.

By default, files are extracted to a directory with the same name as the SIS file.


Specifies the name of the SIS file.


  • The source-filenames specified in the original package file are not stored in the SIS file, therefore DumpSIS creates new filenames for the extracted files.

  • DumpSIS does not reinstate timestamps.

  • If the SIS file is signed, you can display and strip the signatures with SignSIS. DumpSIS does not preserve or display any signing information.

  • CreateSIS can be run on the resultant files to recreate the SIS file.
