So. I kind of like BOMArchiverHelper.app, the default OS X unzipping utility. However, it has quite a number of limitations. Most other unarchivers on OS X have interfaces that I don't like, or just don't work very well. Also, thanks to Windows' idiotic idea of using the current system encoding for filenames, I have tons of archives from Japan with Shift_JIS filenames, which none of the unarchivers on OS X I've tried will handle properly.

And so I, because I obviously don't have enough to do already, get the idea that I need to write a better unarchiver. Features I think it needs include:

• Handle as many formats as possible. Not just Zip and Tar-Gzip, but RAR, 7-Zip, LhA, StuffIt, and anything else you can think of.
• Handle non-UTF8 filenames, perferrably automatically.
• Have a simple and straightforward interface like BOMArchiveHelper.app.
• Not leave .tar files lying around when unpacking .tar.gz files and the like.
• As a side benefit, produce some code that can be re-used to add archive support to Xee (so this whole project doesn't just steal time I could be working on Xee instead).

For actual information on the current state of this project, read on!

So it does, interesting. Will investigate further.

Should unar (beta 0.4 mac) be able to unpack multipart rars? When I use it it only parses the first .rar file and ignores the rest. Using GUI app opens the same multipart rar just fine.

>>970

There was a bug where finding multipart files didn't work unless for files in the current directory. I guess it didn't get fixed yet in 0.4. Add ./ in front of the filename to work around it, or wait for me to get the new versions done.

(Might take a while yet, writing lots of stuff.)

Unarchiver gets my official (but entirely imaginary) "cool tool" award... One question, though: What type of encryption is used if a password is set?

The app description mentions "support for AES encryption", but that is a little sparse...

Thx

>>973

It uses whatever the archive uses, if it's supported. What that is varies a lot. Zip files can use the encryption from APPNOTE.TXT, which is very weak, or AES if they use the WinZip extensions. If you want all the gory details, read either APPNOTE.TXT or the WinZip documentation at http://www.winzip.com/aes_info.htm.

Hi,
I'd like to report an issue with the tar.gz archive, downloadable here:
https://github.com/ryancramerdesign/ProcessWire/

Direct download link:
https://github.com/ryancramerdesign/ProcessWire/tarball/master

(the file is ryancramerdesign-ProcessWire-63c0381.tar.gz)

The Unarchiver performs extraction with no errors or warnings, but the directory wire/templates-admin/ is completely missing.
OS X Archive Utility instead extracts everything correctly.

Tried with The Unarchiver 2.7 on a 10.6.8 MacBookPro late 2008, and with 2.6 on a 10.6.3 hackintosh.

Thx
Riccardo

>>975

Confirmed.

>>975

Also, fixed, thanks to halcy.

I am using the MacOSX version of unar (cli) and I have a question: is there a way to uncompress an archive to stdout instead of a file? I need this to uncompress .7z files and pipe the output to another program.

Thanks!
Jay

>>979

No, but that is a good idea for a feature to add.

I'm not sure how to handle extracting multiple files, though. Maybe just allow extraction of a single file?

>>980

For my purpose allowing only one file will work for me. Thank you for the feature consideration!

Jay

>>977

whoa, that was fast =)

I'm not too great at computers, but I downloaded a .rar file from the internet and when I try and open it up The Unarchiver says the file can't be extracted with this program. Help??

Whether it is Lion or unarchiver, I don't know, but Unarchiver unpacked a zip file into invisible state, a remount did show the files.

I have heard that there are some issues with Lion, can anyone confirm/deny this for me while I decide when to upgrade?

So far it's working like a charm. Only thing I miss for the app is the gorgeous UI justlike one implemented in Entropy.

Great program thank you. But on Lion it's extremely annoying that Unarchiver clears the current selection of files in Finder just because it unarchived a file, because the focus shifts to the top file in Finder, even though the selection as empty when the unpacking of the file is done! Any way to fix that in the next version??

>>992

I'm not sure what you mean. The Unarchiver does nothing to the selection of files in the Finder on Lion here.

Great program thank you. But on Lion it's extremely annoying that Unarchiver clears the current selection of files in Finder just because it unarchived a file, because the focus shifts to the top file in Finder, even though the selection were empty when the unpacking of the completed! Any way to fix that in the next version??

As this thread is just about to fill up, I have opened a new one for further discussion:

http://wakaba.c3.cx/sup/kareha.pl/1314820473/

I think XADMaster has a lot of potential as the definitive compressing/decompressing library. However, I think the fact it is written in Objective-C is a barrier for its general use.

Is there any plan to solve this (eg. providing a C bindings) ?

i've downloaded 2.7.1 twice and am unable to find the interface.

please help.

p.s. i'm a newbie so be gentle

>>997

C bindings is something I'd really like to have, but I haven't had any time to work on, and probably won't in the near future.

hi i just downloaded the the unarchiver and tried to unzip my file but it required a password. i don't know any password?? please help! thank you!
