 Re: 7-Zip 4.62 (Fr)Très bon programme, même si son interface principale un peu sobre comparée à celle de certains programmes commerciaux pourrait rebuter certains.
Note : il semblerait que cette interface n'est exploitable sous Windows 98 qu'à condition d'avoir au moins Internet Explorer 5. |

Re: 7-Zip Theme Manager Gestionnaire de thème de 7-zip
Qu'est-ce? Beaucoup d'utilisateurs de l'archiveur de fichier 7-Zip ont critiqué son aspect nostalgique. C'est exactement où le programme "7-Zip thème Manager", en bref « 7zTM », vient et offre les fonctionnalités suivantes: • Thèmes de la barre d'outils - changer l'apparence de la barre d'outils de 7-Zip. • Filetype thèmes - changer l'apparence de fichiers archivés, par exemple dans l'Explorateur. • 90 Thèmes de barre d'outils et de 22 Filetype thèmes intégrés. • Modification de l'icône de SFX (archive auto-extractible) est maintenant possible. • Recherche automatique ou manuelle du dossier d'installation de 7-Zip. • Activation pratique des thèmes en un clic. • Prévisualisations de thèmes intégré directement dans le programme. • Interface utilisateur multilingue. • Mise à jour en ligne pour mettre à jour des thèmes et des caractéristiques. • Possibilité de créer vos propres thèmes. • Prend en charge 7-Zip 32-Bit et 64-Bit.

Re: 7-Zip 15.12 (Fr) Wow! Enfin une version définitive (release) cinq ans après la dernière en date.
A noter que 7-zip peut maintenant ouvrir les fichiers compressés avec (Win)RAR version 5.x. |

Pour info, concernant les performances de compression Attention, certains ont remarqué avec la nouvelle version 15.12 que le gain d'espace était moins bon qu'avec la 9.20 (précédente version stable), avec exactement les mêmes réglages et ensembles de fichiers à archiver. Cette différence peut, selon les cas, être plus ou moins significative.
Ceci est lié au fait que, depuis la 15.06 beta, 7-zip ne trie plus les fichiers par extension avant de les ajouter à une archive solide. Si vous voulez rétablir ce comportement, il suffit d'ajouter "qs" (sans guillemets) dans le champ "Paramètres", en bas à gauche de la fenêtre "Ajouter à l'archive". Le logiciel gardera ce paramètre en mémoire. Source de l'info : http://sourceforge.net/p/sevenzip/dis ... 797/thread/6cc0d82c/#7a6b |

Simple et épuré J'adore ce logiciel avec juste un bémol! la version native 7Z et très peu reconnue par les autres logiciels de compactage. Il vaut mieux paramétrer 7zip avec des fichiers en sortie en format zip si vous partagez lesdits fichiers.

Privilégier la compatibilité ou la performance ? En réponse à arkonide, j'aurais tendance à dire que si on continue à diffuser du .zip par souci de compatibilité, alors ça ne va pas aider le format .7z (ou n'importe quelle "nouveauté") à devenir populaire, alors pourtant qu'il le mérite bien puisqu'en règle générale il permet d'obtenir des archives plus légères, parfois de manière _très_ significative.
Par ailleurs la majorité des archiveurs populaires savent décompresser du .7z, pourvu qu'ils ne soient pas dans des versions trop anciennes. Pour prendre un exemple populaire, WinRAR prend en charge la décompression du .7z depuis des années. Enfin, même si on diffuse des archives en .zip, l'utilisateur final peut rencontrer des problèmes avec, car la prise en charge de ce format directement dans l'explorateur Windows est loin d'être parfaite (par exemple, quand l'archive contient des sous-dossiers, ça se complique). |

Re: v 18.06 Ce serait sympa de remettre le nom du logiciel dans le sujet, et ce pour tous les logiciels que tu "commentes". Je suis obligé d'aller voir à quelle fiche de logiciel correspond le commentaire (la plupart du temps pour des logiciels que je n'utilise pas).
Merci. |

20.00 Alpha 7-Zip now supports new optional match finders for LZMA/LZMA2 compression: bt5 and hc5, that can work faster than bt4 and hc4 match finders for the data with big redundancy.
The compression ratio was improved for Fast and Fastest compression levels with the following default settings:
Fastest level (-mx1) : hc5 match finder with 256 KB dictionary.
Fast level (-mx3) : hc5 match finder with 4 MB dictionary.
Minor speed optimizations in multithreaded LZMA/LZMA2 compression for Normal/Maximum/Ultra compression levels.
bzip2 decoding code was updated to support bzip2 archives, created by lbzip2 program.
Some bugs were fixed.
New localization: Turkmen.

v 21.04 beta v 21.04 beta 2021-11-02
-------------------------
- 7-Zip now reduces the number of working CPU threads for compression,
if RAM size is not enough for compression with big LZMA2 dictionary.
- 7-Zip now can create and check "file.sha256" text files that contain the list
of file names and SHA-256 checksums in format compatible with sha256sum program.
7-Zip can work with such checksum files as with archives,
but these files don't contain real file data.
The context menu commands to create and test "sha256" files:
7-Zip / CRC SHA / SHA-256 -> file.sha256
7-Zip / CRC SHA / Test Archive : Checksum
The commands for command line version:
7z a -thash file.sha256 *.txt
7z t -thash file.sha256
7z t -thash -shd. file.sha256
New -shd{dir_path} switch to set the directory that is used to check files
referenced by "file.sha256" file for "Test" operation.
If -shd{dir_path} is not specified, 7-Zip uses the directory where "file.sha256" is stored.
- New -xtd switch to exclude directory items from processing.

that will be used for compressing.
- New switch -mmemuse={N}g / -mmemuse=p{N} to set a limit on memory usage (RAM)
for compressing and decompressing.
- Bug in versions 21.00-21.05 was fixed:
7-Zip didn't set attributes of directories during archive extracting.
- Some bugs were fixed.

v 21.07 21.07 2021-12-26
-------------------------
- 7-Zip now can extract VHDX disk images (Microsoft Hyper-V Virtual Hard Disk v2 format).
- New switches: -spm and -im!{file_path} to exclude directories from processing
for specified paths that don't contain path separator character at the end of path.
- In the "Add to Archive" window, now it is allowed to use -m prefix for "Parameters"
field as in command line: -mparam.
- The sorting order of files in archives was slightly changed to be more consistent
for cases where the name of some directory is the same as the prefix part of the name
of another directory or file.
- TAR archives created by 7-Zip now are more consistent with archives created by GNU TAR program.

Re: 7-Zip v23.00 beta Changements
v 23.00 (2023-05-07) C'est une version Beta https://www.7-zip.org/a/7z2300.exe https://www.7-zip.org/a/7z2300-x64.exe - UDF support was improved to UDF version 2.60. - 7-Zip now can use new ARM64 filter for compression to 7z and xz archives. ARM64 filter can increase compression ratio for data containing executable files compiled for ARM64 (AArch64) architecture. Also 7-Zip now parses executable files (that have exe and dll filename extensions) before compressing, and it selects appropriate filter for each parsed file: - BCJ or BCJ2 filter for x86 executable files, - ARM64 filter for ARM64 executable files. Previous versions by default used x86 filter BCJ or BCJ2 for all exe/dll files. - Default section size for BCJ2 filter was changed from 64 MiB to 240 MiB. It can increase compression ratio for executable files larger than 64 MiB. - UDF: support was improved. - cpio: support for hard links. - Some changes and optimizations in WIM creation code. - When new 7-Zip creates multivolume archive, 7-Zip keeps in open state only volumes that still can be changed. Previous versions kept all volumes in open state until the end of the archive creation. - 7-Zip for Linux and macOS now can reduce the number of simultaneously open files, when 7-Zip opens, extracts or creates multivolume archive. It allows to avoid the failures for cases with big number of volumes, bacause there is a limitation for number of open files allowed for a single program in Linux and macOS. - There are optimizations in code for 7-Zip's context menu in Explorer: the speed of preparing of the menu showing was improved for cases when big number of files were selected by external program for context menu that contains 7-Zip menu commands. - There are changes in code for the drag-and-drop operations to and from 7-Zip File Manager. And the drag-and-drop operation with right button of mouse now is supported for some cases. - The bugs were fixed: - ZIP archives: if multithreaded zip compression was performed with more than one file to stdout stream (-so switch), 7-zip didn't write "data descriptor" for some files. - ext4 archives: 7-Zip couldn't correctly extract symbolic link to directory from ext4 archives. - HFS and APFS archives: 7-Zip incorrectly decoded uncompressed blocks (64 KiB) in compressed forks. - Some another bugs were fixed. |
