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.
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.
Mac OS X 10.4 or later (OS X 10.3.9 could also work).

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. | |

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.

TASKMAN It's been replaced with one that should actually work. http://sixtyfive.xmghosting.com/2008/03/09/new-7zx-17-alternative/

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...

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.

MARIVAUX This is definitely the best 7z application for the Mac--I'd be happy to see it able to open with the option to add a file, instead of drag and drop only, but otherwise, it can even preserve a resource fork, which is impressive for an application that uses a windows-originating compression technique.

EJI 7zX created an invisible or "hidden" temp file (.7zXtemp/) on my desktop, which wreaked havoc during a backup operation with Carbon Copy Cloner. What happened was that somehow my entire user directory was aliased in this temp file, causing the clone operation to copy data infinitely (since the alias existed in the alias too). I have no idea how this happened, but I'm wary about reinstalling 7zX now that I've upgraded to Leopard. Has anyone else experience this? Was it a bug left over from earlier versions of this compression app?
