site_archiver@lists.apple.com Delivered-To: installer-dev@lists.apple.com In the Info.plist, IFPkgFlagInstalledSize is stating: 30718. So we're not dealing with bytes, or KiloBytes. Any package with LOTS of files can have huge differences in sizes. Any idea? _______________________________________________ Do not post admin requests to the list. They will be ignored.

Would someone know what the unit is supposed to be for the IFPkgFlagInstalledSize? It's one of the undocumented flags you can find in some Info.plist and for which the unit seems to come from another galaxy. For instance, in the Safari 1.2 package, the archive weights 21.3 (or 21.8) MB uncompressed. In iTunes 4.something package, we have an archive of 26.1 (or 26.5) MB uncompressed and IFPkgFlagInstalledSize is stating: 27846. In this case, this could be some kind of KiloBytes but not the official one. It is indeed KiloBytes with each file rounded up to a 4k boundary, since this is a "better" estimate of the actual space it will take on disk. Of course the block size of your filesystem may not be 4k. Chris This email sent to site_archiver@lists.apple.com
