- RAR - What's new in the latest version
-
-
- Version 2.50
-
- 1. Both packing speed and compression ratio have been improved.
-
- 2. WinRAR is now able to process ZIP archives without calling
- external programs. Supported operations for ZIP archives:
-
- - extracting;
- - testing;
- - creating and updating;
- - deleting;
- - repairing;
- - commenting;
- - converting to SFX (self-extracting) archive;
-
- To handle ZIP archives, WinRAR incorporates compression code
- by the Info-ZIP group, which is used with their permission.
- There are no extra charges or costs due to the use of this code,
- and the original compression sources are freely available from
- ftp://ftp.cdrom.com/pub/infozip/
-
- Note that ZIP archives are supported only by the GUI WinRAR.EXE
- Console RAR.EXE and UNRAR.EXE are able to process only RAR archives.
-
- 3. New options in "Add" dialog:
-
- a) "Archive format":
-
- Allows format selection (RAR or ZIP) of new archive.
- Read online help for detailed formats consideration;
-
- b) "Erase destination disk contents before archiving":
-
- Delete all files and folders from the destination disk
- before creating an archive. Works only with removable disks
- and if used when creating volumes, erasing will be performed
- before the creation of each volume;
-
- c) "Add only files with attribute "Archive" set":
-
- Add only those files, which have the "Archive" attribute
- set on. Useful for backup operations;
-
- d) "Clear attribute "Archive" after compressing"
-
- Clear the "Archive" attribute on compressed files.
- Useful for backup operations.
-
- 4. Changes in "View" command:
-
- a) Size of viewed file in the internal viewer now is limited
- only by the amount of available memory. Previous limitation
- is removed;
-
- b) It is possible to change the default viewer font using
- command "Set font" in "View" menu of viewer window.
-
- 5. Changes in "Delete" command:
-
- a) Usual (non-archived) files now deleted to the Recycle Bin.
- Press Shift-Del instead of Del, if you wish to delete files
- as before;
-
- b) "Delete" command now can delete non-empty folders.
-
- 6. New "Estimate" command allows to roughly and quickly estimate
- compression ratio of selected files and folders. Do not wait
- to get an exact result from this command, nevertheless it can
- show is it worth to spend time to compress selected data.
-
- 7. "Extract" and "Test" commands now are accessible also outside
- of archives. If you select a group of files and folders and use
- one of these commands, WinRAR will search for archives in the
- selected data to process all archives which are found. It makes
- archive group operations much simpler. For example, if you
- select all files and folders in a root disk folder and press
- "Test", all archives on this disk will be tested.
-
- 8. Changes in "Extract to" command:
-
- a) "Update mode" option;
-
- b) "Overwrite mode" option;
-
- c) "Clear attribute "Archive"" option;
-
- Clear attribute "Archive" on extracted files.
- Useful for backup operations.
-
- d) "Keep broken files"
-
- Do not delete extracted files having incorrect CRC (checksum);
-
- 9. Changes in "SFX" command: this command now allows to select the
- SFX module used for archive conversion.
-
- 10. Changes in "Info" command:
-
- a) RAR specific options now moved to a separate property sheet
- dialog;
-
- b) Size of SFX module is displayed in addition to "SFX" string
- in archive type.
-
- 11. "Browse for folder" command in "File menu" allows the selection
- of a new current folder from folders tree.
-
- 12. "History" menu contains the names of the last opened archives.
- You may select an archive from this menu to open the archive
- again.
-
- 13. "Favorites" menu contains the names of the preselected
- folders and archives. You may select an item from this menu to
- open the archive or go to the folder. Use "Add to favorites"
- command (Ctrl-F) from the same menu to add a new item to the
- favorites list.
-
- 14. "Settings" dialog is seriously modified. Read online help
- for details. Most important changes:
-
- - General/Interface/Reuse existing window:
-
- If user tries to open a new archive, executing "WinRAR
- <arcname>" command and an another WinRAR window is already
- open, the archive will be opened in the existing window. If
- this option is not enabled, a new window will be created;
-
- - Paths/Start-up/Restore last working folder on start-up:
-
- If this option is enabled, WinRAR will set last viewed folder,
- when executed without parameters;
-
- - Compression/Archive format:
-
- Select the archive format (RAR or ZIP) proposed by default
- in "Add" dialog.
-
- - Compression/Volume options/Always put recovery record:
-
- Always put recovery record to volumes regardless of
- "Put recovery record" option in "Add" dialog;
-
- - Compression/Volume options/Independent solid volumes:
-
- When this option is enabled, WinRAR tries to create solid
- volumes which are independent one each another, so if one
- volume is lost, files in following volumes may still be
- accessible. Note than sometimes this option cannot help, for
- example, if volumes contain one large file. This option
- slightly decreases solid volumes compression ratio, but
- seriously increases reliability due to data loss because of
- poor media quality. It is not recommended to switch off
- this option.
-
- 15. "View log" command in "Options" menu show RAR log file contents;
-
- 16. It is now possible to integrate WinRAR to Windows shell.
- If you selected "Integrate WinRAR into shell" option
- when installing WinRAR, the following features are available
- in Windows shell (explorer):
-
- a) dropping files to an archive icon will add these files
- to the archive;
-
- b) if you drop an archive to a folder using the right mouse
- button, "Extract files" item will be added to the menu;
-
- c) "Extract files" item added to archives context menu,
- which appeared after the right mouse button click on an
- archive icon;
-
- d) "Add to archive" item added to files and folders context
- menu;
-
- e) Archive specific information sheet is added to archive
- properties. If an archive has a comment, it is shown
- as a property sheet.
-
- 17. You may press the "Background" button in command window during
- archiving or extracting operation to minimize WinRAR to tray.
- In this mode WinRAR slightly decreases its priority and continues
- operation in the background.
-
- 18. Yellow progress bar, showing total compressed size, displayed
- during archiving operation.
-
- 19. "Drives" menu is moved from toolbar to a small icon on the
- status bar. It is also acessible using Ctrl-D shortcut.
-
- The second status bar icon calls "Enter default password" dialog.
-
- 20. CRC of packed data is now stored for file parts split between
- volumes. It allows localization of a damaged volume, if volumes
- set contains one large compressed file.
-
- 21. New command line switches:
-
- a) -sv - create independent solid volumes. This switch has
- the same meaning as the option "Independent solid volumes"
- described above;
-
- b) -ac (clear "Archive" attribute) now can be used not only
- when archiving, but also when extracting files to clear
- "Archive" attribute on extracted files;
-
- c) -ap<path> - set path inside archive. It allows to add files
- to a specified archive folder when archiving or to remove
- the specified part of path from file names when extracting;
-
- d) -dh - open shared files. Enables to process files opened
- by other applications for writing;
-
- e) -- switch stops further switches scanning. It can be useful,
- if you need to use in the command line a file or archive name
- beginning with '-' character.
-
- 22. Command "CW" (write comment to file) can now be performed also
- by GUI WinRAR. In previous versions it was supported only by
- console RAR.
-
- 23. Significantly improved speed of processing large file lists.
-
- 24. If in WinRAR you press Enter or double-click on an executable
- file within an archive, all archive contents will be extracted
- to a temporary folder, WinRAR will then start the selected file,
- wait until it is finished and removes this temporary folder.
- Such feature allows, for example, to install applications
- directly from archives.
-
- 25. DOS version of RCVT archive converter is replaced by
- Win32 console version.
-
- 26. Some unnecessary code is removed from SFX modules,
- so their size was significantly reduced. For further size
- decrease SFX modules were compressed using UPX tool
- written by Markus F.X.J. Oberhumer and Laszlo Molnar
- (http://wildsau.idv.uni-linz.ac.at/mfx/upx.html).
-
- Uncompressed versions of SFX modules are also provided
- in the archive UnpSFX.rar. They can be useful, if you want to
- modify SFX resources.
-
- In Default.SFX (RAR GUI SFX) and Zip.SFX (ZIP GUI SFX)
- it is possible to set some additional parameters, for example,
- specify file name, which will be executed after extracting
- SFX contents. Look into "Self-extracting modules" topic of
- winrar.hlp for details.
-
- 27. Comparing with the previous version some files were added to
- the distributive, some removed, so as to reduce the amount of
- unnecessary files in WinRAR folder it is a good idea to first
- uninstall any previous version and than install the new one. Do
- not forget to save your registration name and key from your
- rar.ini before doing this, if you do not have a copy of this
- information elsewhere.
-
- But note that WinRAR version for Windows 3.x + Win32s
- is no longer supported. So if you need to use WinRAR under
- this platform, save winrar.exe from the previous version.
