DESCRIPTION
7zX is a file archiver with high compression ratio. Compression ratio results are very dependent upon the data used for the tests.
Usually 7zX compresses to 7z format 30-70% better than to zip format, and 2-10% better than most of other zip compatible programs.
7zX currently supports tar, zip, gzip, bzip2, UNIX compress, 7z, s7z and various kinds of segmented archives.
It supports Macintosh resource forks and Spotlight metadata, and can also create Self-Extracting archives.
WHAT'S NEW
Version 1.7.1:
- The bug that caused 7zX to produce bus errors on certain machines should be now fixed.
- Software Update should work correctly once again.
REQUIREMENTS
Mac OS X 10.4 or later (OS X 10.3.9 could also work).

TINGTING Thanks for this app. I recently discovered 7zip. Much smaller files. Open source. Totally cool. Works great. Free encryption of files and folders too. Thanks again.

YULETIDE Great app! Seems to be the best front-end (for compressing) for 7z around... and 7z is super-awesome. It isn't anything close to what's available on Windows (shell integration! so nice...), but its free and it works better than the rest. That being said, a GUI would be SUPER nice (being able to do things other than through drag & drop). Also, having the app decide if I want to compress/decompress is a bit annoying. I should be able to set a pref so it only tries decompressing for certain formats (so I can recompress a zip or something, for instance). Oh, and http://sparkle.andymatuschak.org/ would be a nice addition too! Keep up the great work...

MOMAC14 I created an encrypted archive and sent it to another mac I own . While opening the archive I was presented with the password screen . I clicked cancel and the archive opened . Has any one else come across this & is this something to be concerned about .

ZANGIEF I tried this, same thing happened to me. I compressed a PNG with "test" as the password, then tried to open the archive. I clicked "cancel" in the password dialog box, and 7zX's main window noted that the password was wrong, and that the file wouldn't be expanded. The file was expanded anyway, though, and I ended up with the same PNG I compressed. Alright developer, get in here and fix it.

TASKMAN Inserting a wrong password or canceling the operation causes 7zX to generate 0 KB files, and display CRC errors in the main window. Archive contents are actually ENCRYPTED using AES-256, and cannot be decrypted unless you know the correct key.

CORPSECORPS Odd behaviors. Sometimes it wants to compress a zip file instead of unzipping it. Using it to unzip files, i get a folder called __MACOSX which in turn contains a folder with the name of what i'm unzipping. A second separate folder with the name of the item i'm unzipping appears in the same directory with the actual contents of the archive. | |

TASKMAN Certain archives are created using a proprietary variant of the AppleDouble encoding, which is currently not supported. Until we work on a fix, you should expand those files using Apple's Compression Utility.

YULETIDE Seems the new version is causing trouble... after upgrading only to see 7za crashing due to bus errors, I followed this temporary fix from the 7zx forums: Downgrade to 1.6.7: http://sixtyfive.thesneaky.com/temporary/7zX_1.6.7.dmg | |

TASKMAN Only if you are getting bus errors. Most likely doesn't apply to Mac OS X 10.5 users.

M-RICK This new version simply doesn't work for me ... It will ask you the settings to compress and may compress the file, but not archive made and available nowhere ... I didn't have this with the previous version.

YULETIDE Can't seem to compress pdf files... it just tries to expand them. Strange.

YULETIDE Hm. It works for some. Perhaps they have internal compression that confuses it?

YULETIDE I figured it out. I was trying to compare compression ratios between 7z and the much faster ZIP, so I had already zipped the pdf. Then 7z tried to expand (i dropped the pdf). Though it didn't actually do any expansion. When I deleted the zip file, it compressed the pdf just fine.

TASKMAN This used to happen when you had an archive with the same file name in the same folder as the items you were trying to compress. At that point, 7zX should have created a 7z archive, but rather noticed your ZIP archive and focused on that rather than launching the compression routines. Fixed in version 1.7. :)

MACMUSER I couldn't get it to make segmented archives. Selected the segment size, still only got one file.
