- Zip 3.0f
- We have posted Zip Beta 3.0f, September 24th 2007. This is a beta
- release, but is more or less complete. See the file WhatsNew for
- a list of major features implemented and what's left.
- The archive reading and writing code in this beta has been redone to
- support split archives. We've extensively tested the code over the
- last year, but you should thoroughly test it yourself before relying
- on it. Also note that Unicode support is preliminary and may change
- before release, but currently there seems agreement between Info-ZIP
- and others on how to handle storing UTF-8 paths and that approach is
- implemented in Zip 3.0.
- Please test this beta and let us know if we're ready to officially
- release Zip 3.0.
- New things in Zip 3.0f
- - Split archives - Zip now can create and indirectly update split
- archives
- - Unicode support - Zip now stores Unicode paths that should be more
- portable across character sets and languages and Zip now can
- read Windows file names in most all character sets using Unicode,
- but this support is preliminary and may change by release
- - bzip2 - bzip2 compression is now supported
- - Console writing - Messages to the console are more consistently
- formatted
- - Streaming - Directories are now handled better when streaming
- - Date range - Can now use -t and -tt to set a date range
- - UnZip Check - Check if UnZip 6.00 or later is available for
- testing a Zip64 archive
- - License - minor updates to the license
- - Difference mode - A new option -DF (--dif) creates an output archive that
- includes only files changed or added since the input archive was created,
- and might be useful for incremental backups
- - File Sync - New option -FS synchronizes the entries in an archive with the
- files on the file system, adding, updating, and deleting entries as needed,
- creating an updated archive that should be the same as a new archive, but
- since existing entries are copied and not recompressed it can be faster
- - Fix options - Options -F and -FF now fix split archives
- - Copy Mode - This new mode allows selecting archive entries to copy
- to a new archive
- - Case matching - On Windows and VMS, option -ic (ignore case) turns off
- case-sensitive matching of command line input patterns when matching
- entries in an archive
- - Windows OEM - With this compile option, file names are saved on
- Windows in the local OEM character set, as some other zips do
- - Windows Archive Bit support - On Windows can now select files
- using the Windows archive bit
- - Global dots - Can now set quiet mode, but output progress dots every
- so many bytes read, settable from KB to TB, allowing progress to be
- displayed for large archives without the screen scrolling
- - Empty archives - Options -i or -i@ can now output empty archives,
- which is useful in some scripts
- - Keep extra fields option - Option -X- allows passing through extra
- fields that Zip does not process
- - Large file encryption bug fixed - Fix for bug that very rarely
- results in bad data being stored when deflating and encrypting
- uncompressable large amounts of data and resulting in CRC errors
- - Show Files option - Can list the files that would be operated on
- - Delete date bug fixed - Bug when using -d with -t or -tt is fixed
