InstallShield PKG is a format usually encountered as a file named setup.pkg. Such a file is included in some installers made by the InstallShield installation software for Windows.
[edit] Discussion
Authoritative information about PKG's purpose has not been found. It's sometimes described as "InstallShield compiled setup package". It is a binary file, relatively small, and appears to primarily contain filenames.
[edit] Identification
PKG files are observed to start with bytes 4a a3, and have 02 00 00 00 at offset 6.
