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 Mac resource forks and Spotlight metadata, and can also create Self-Extracting archives.

As per the developer's site, the HTTP links for 7zX appear to be down. In the meantime, we have a copy available hosted here on MacUpdate accessible via the 'Download Now' link above.
I apologize for the inconvenience.

Does anyone keep track of things here?
7zx is something I really like and I needed to get a new copy. This is what I find? Thanks to those putting up fileserver links.

Archive contents are actually ENCRYPTED using AES-256, and cannot be decrypted unless you know the correct key.

This behavior should be fixed so that the result of pressing the Cancel button is that no files or folders are created.

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.

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. :)

Selected the segment size, still only got one file.

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?

It won't work if I try to compress a folder with spaces in his name. All goes well if I replace them with underscores.

Could you tell me more about the compression options you are using? Thanks.

version 1.6.5 runs for a moment then quits with no output. iMac G5, OS X 10.4.9.
The file I try to compress has a long name with lots spaces (it is an eml email message, 100KB. file name is subject line, about 110 regular english letters, numbers, punctuation characters).
Drag to 7zx v165, little window shows the following then quits, no compressed file to be found.
"Total
"Folders: 0
"Files: 0
"Size: 0
"Compressed: 0"
Do not see any other window, so no way to "set any options" since the program has no direct user interface, no way to set any preferences.
If I change the source file name by replace all spaces with dashes, then 7zx does work, gives the Add To Archive window and does create an archiveof it.
P.S. 1) the small status result window goes away very fast, so very hard to grab a screen snap of whatever it says.
P.S. 2) though I have high hopes for the 7zx program, and appreciate your efforts, I am mystified by your website. I have never been able to get any details or files directly off the site. So I just get the program only from MacUpdate.
Also, that is the reason I am writing the long comment here rather than direct to your site. Sorry about that. Hope the details are useful.

Please tell me what email address to use. I have looked through the 7zx download files and docs but there is no email address. Only physical address and website link.
When I go to the website, it does not provide email address. Only a 'comments' box under the software blog topic. That would not work very well for pasting in data files.
Thx.

Regarding the overwriting-existing-files issue, you are right: I will release an updated version of 7zX as soon as I can.

However, the files were not extracted into that folder on the ext hd, but rather to my startup disk (which soon reached capacity and complained of being full). I cancelled the process, but now can't find where the files have been extracted (can't even find them through search--are they saved in some temp format?). Please help, I've essentially lost 1+gb of free space and don't know where it's gone.
