This is a major upgrade +from Zip 2.32, the current Zip 2.x release. A quick summary of +features is below, but see the file WhatsNew for the detailed list +of major features and upgrades as well as what's on the list for +Zip 3.1. Send in your feature suggestions and bug reports. + +Quick list of major changes in Zip 3.0: + +- Large files. Support for files and archives greater than 2 GB using + large file I/O and the Zip64 extensions. Also can now have more + than 64K entries in an archive. + +- Split archives. Zip now supports split archives, zip archives + split into a set of files that can then be stored on removable media + for instance. + +- Unicode. If Unicode support is enabled and supported on the system + Zip is run on, Zip now can read paths not in the current character + set and store those paths in portable UTF-8 format. These Unicode + paths can then be used to partially or fully recreate the paths on + other systems depending on the character set support provided by + the unzip on the receiving system. In particular, this allows + portability of paths between Windows and Unix. Unicode comments + are also supported on systems where UTF-8 is the current character + set. Unicode comment support for other systems is expected in + Zip 3.1. + +- New command line parser. This new parser allows for command line + permuting, where options can appear almost anywhere on the command + line. This allows adding options to the end of the command line, + for instance. It also supports long options, allowing for + more readable command lines, and also allows lists for the -x + exclude and -i include options to appear not just at the end of + the command line. And some bugs in command line processing in + Zip 2.32 have been fixed. + +- Unix 32-bit UIDs/GIDs. Now UIDs/GIDs larger than 16 bits are + supported, but UnZip 6.0 is needed to restore these larger + UIDs/GIDs. If Zip detects that the current system does not use + 16-bit UIDs/GIDs, the old 16-bit UID/GID storage is not used + as putting 32-bit UIDs/GIDs into 16-bit fields can cause + problems. + +- New modes. Additional archive modes have been added, including a + difference mode for supporting incremental backups, a file sync + mode for synchronizing an existing archive with the current file + system (which can be much faster than creating a new archive), and + a copy mode that allows copying entries from one archive to another. + +- Compression using bzip2. Now can add bzip2 compression as a + compression option in Zip. bzip2 compression can result in much + more compact entries in some cases, but the user should verify + that bzip2 is supported on the target unzip before using this new + compression choice. + +- New Windows dll. The Windows dll has been updated to support the + new Zip64 large file and larger number of entries limits. This + new dll is not backward compatible with the Zip 2.32 dll, as the + arguments to the dll have been updated to support the added + capabilities, but modifying existing programs to use the new dll + should be simple. See the included Visual Basic example project + for details. + +- Better streaming and piping. Zip now has better support of + streaming and piping and handles Unix FIFOs (named pipes) better. + +- Gobs of new progress information. Zip can now output progress + information, such as how many entries processed and to go, how + many bytes processed and to go, and adjustable size progress + dots. If the initial file scan takes longer than about 5 + seconds, Zip now outputs dots during the scan to avoid a long + period of quiet. Zip can also now generate log files. + +- Updated archive fixing. The archive fixing capability is + slightly improved, and now can fix split archives. + +- Windows Archive bit support. The Windows archive bit is now + supported, though the new difference mode is probably more + reliable than relying on the Windows archive bit for creating + incremental backups. + +- File lists. Zip can list the files that would be added to an + archive as well as the files in an existing archive. + +- Extended help. A new extended help option lists a very terse + summary of the major features of Zip and how to use them. + +- Many bug fixes. + +As always, see the Zip manual page for details on what Zip has and +how to use all features. + +Enjoy! |
