AZip / News: Recent posts

New in version 2.7:

• Tabs: each archive subwindow has an own tab on a tab bar (new). This makes the handling of AZip easier to understand.
• Temporary directory: you can optionally set a specific temporary directory - typically, in a RAM disk - for AZip's operations such as archive recompression. Your HD or SSD will thank you.
• Fix: sorting column and direction are preserved on operations that modify a Zip archive (delete, add, update, recompress, etc.).
• Single instance: when Zip archives are opened and AZip is already running, those archives are opened in that running instance - thanks to Nicolas Pinault (DrPi) for that feature!

New in version 2.6: sorting is much faster.

• for 1024 items, sorting is ~150 times faster on one desktop PC, ~400 times faster on another one
• for 65536 items, sorting is ~2800 times faster on one desktop PC, ~4300 times faster on the other one

Details in doc/azip_work.xls

New in version 2.5:

Support for Zip_64 archives.

The Zip_64 format extension is needed when there are more than 65535 entries or more than 4 GiB data for a single entry's compressed or uncompressed size, or for a whole archive.

• Display on "Select all" & "Unselect all" is faster
• Command "Invert selection" (Ctrl-I) was added
• Sorting is faster on columns with numerical content
• Sorting on data sizes is exact, even if the same amount of KiB, MiB, or GiB is displayed

The long-awaited Windows Explorer integration is there:

For files:

For folders:

This integration is activated upon installation or on demand via the Manage button:

Coming soon (for the next AZip release) is a stronger and faster compression specifically for Audacity files (.aud, .au).
More about it in this article.

AZip can now install itself (if requested)!

• Option for a default extraction directory (1st screenshot)
• Drag & Drop from a folder within AZip to Windows Explorer or the Desktop
• Context menus within AZip (2nd screenshot)

A new View / Select columns menu entry allows you to select the columns that you find useful to be displayed:

Presentation is available as PDF and PPT.

The whole Ada Devroom day at FOSDEM 2019 is visible here .

• Added buttons for New, Open and Toggle view commands.
• Cases where Zip format capacity is exhausted are properly handled.
• Sorting is a bit faster.

• AZip features now the long-awaited drag & drop from AZip to Windows Explorer / Desktop.
• AZip can operate in a "no trace in registry" mode. All you need is to put a dummy file
  with the name "azip.cfg" in the same directory as the executable, azip.exe. If
  azip.cfg is read-only, user settings won't be remembered for next usage, otherwise
  settings will be recorded in azip.cfg instead of in the registry.... read more

Improvements in the search tool.

• Uses Zip-Ada v.53 : more resistant to invalid / fuzzed archives
• Drag & drop more intuitive on main window, if child window is maximized (rev. 248)
• Small UI improvements (rev. 249, 250)

Minor glitch fixed; recompressed files pass tests with 7-Zip 17.01 beta.

Keyword search function is much faster and doesn't need to hold entire uncompressed entries in memory (was an issue when searching on large files).

Minor addition: on Windows 7+, the AZip taskbar icon shows the progress of current operation.

New minor features in this version are:

• An "Add folder" menu command - note that this feature is already implicitly available via drag-and-drop
• Begin of a "Quick help" dialog box
• Access to AZip web page

AZip features now the long-awaited recompression tool.
The tool uses an algorithm-picking approach for improving a zip archive's compression.

Other improvements compared to version 1.32:

• Glitches fixed upon aborting of any operation
• (Windows) target folder is opened after extraction

Two issues were resolved:

• (Windows) AZip crashed systematically when two or more archives were opened via drag & drop on a blank archive
• The archive updater had a heavy write-close-delete cycle of a temp file with .zip extension. Using .tmp and deleting only once at the end of update operation prevents random update failures on Windows with certain antivirus programs

• Bug fix: on extracting a selected folder, say 'lz', prevent exctracting another sibling folder, e.g. 'lzma'
• Progress box display refresh a bit less frequent
• Added [i] toolbar icon for archive properties
• Properties display uncompressed sizes correctly when above 4GB

• Deflate format - the Zip standard - is now used for quick compression (e.g for adding files, updating an archive), instead of Shrink
• More precisely, the Deflate_1 method in Zip-Ada library is used.
• Progress box shows the type of ongoing operation

• When extracting files from archive: times are restored correctly during Daylight Saving Time (DST)
• After archive update or search through archive, flat view is toggled and results are sorted upon a single click

Version 1.27 has two additions:

• encryption is possible upon dropping files into an archive window
• a "Properties" box was added, with some statistics

This version adds encryption.
Up to now AZip was only able to decrypt data from archives.
