7 zip for os x archive#
When I extracted files with 7-Zip File Manager from this 881-megabyte archive using Windows Explorer's context menu, and it extracted only a 180-megabyte file and issued a warning about data after the payload, I wrongly assumed that 700 megabytes of data were after the payload, not just 2 kilobytes. I also believe that it would help if there were more options to enable the switch -t* in 7-Zip File Manager, such as:Ī way to open and extract archives with the switch -t* from within 7-Zip File Manager Ī way to extract archives with the switch -t* from Windows Explorer's context menu.

I removed the "tail" from the package file, and was still able to perform a full installation, and to extract all data with xar, on OS X without errors.I found the same block of 2.204 bytes elsewhere in the heap (it was a small fragment of one of the files named Payload).it is located after the end of the last file in the heap.it is not listed in the "table of contents" XML document of the XAR archive.More detailed information about warnings in the 7-Zip File Manager extraction dialog box, at least the same shown in 7-Zip Console (in this case, Type, Physical Size, Tail Size, etc.).Īt least in this case, I believe it is safe to assume that the "tail" is meaningless data, for the following reasons: pkg, especially when they have more than one file named Payload within Ī way to open archives with the switch -t* from within 7-Zip File Manager Ī way to extract archives with the switch -t* from Windows Explorer's context menu Improvements in the way 7-Zip detects the type of archives with the extension. So, I would make these suggestions, if I may: This option does not seem to be available if I open the archive from within 7-Zip File Manager, though.ħ-Zip Command Line Version User's Guide states that "If -t switch is not specified, 7-Zip uses extension of archive filename to detect the type of archive", and I assume that this also applies to 7-Zip File Manager. Well, I just noticed that in Windows Explorer's context menu there is an option "7-Zip > Open archive > *" that will list the whole contents of the archive in 7-Zip File Manager. The command "7z x arcname.pkg" will only extract the same file named Payload~ that 7-Zip File Manager does. xml, similar to the one created by "xar -xf arcname.pkg -dump-toc=.xml" (the contents of both seem to be the same, but shown in a different order).

The command "7z x arcname.pkg -t" will extract the same files as "xar -xf arcname.pkg" plus a file named. The command "7z l arcname.pkg -slt -t*" does list the whole contents of the archive, but issues a warning: I misspelt the name of the command I used on OS X, it was actually xar -x ("xar -xf arcname.pkg"). First of all, thank you for your excellent work and prompt reply.
