The Unarchiver, part 2 (486)

1 Name: !WAHa.06x36 : 2011-08-31 12:54 ID:EvuKrlQD [Del]

As the previous thread filled up, here is part 2 of the The Unarchiver thread.

It is much better to post bugs on the bug tracker, rather than in this thread! Anything posted on the bug tracker has much less chance of being forgotten by me!

So, post bugs here:

Also, remember that if you post a bug about a file that is not work, you must also post the file itself, or else there is nothing I can do about it!

That's what I'm saying, it says it's fixed in the bug entry. But- selecting all segments of the multi-part, opening- and the queue has one for each part.

If there were a preference to overwrite on the same name this wouldn't suck nearly as much, other than wasted time.

But thats only if it's not set to move the archive to trash after processing. Then of course, it will get an error on the subsequent extractions, halting the whole process.

Verified that I am using the latest download, 3.10.1.

I suggest filing a new bug for it, so I'll remember to look at it when I get around to the next update.

MacOS unarchivier last version.

No. But what kind of non-printable characters? You might be able to do it anyway, if you pick the right encoding.

when attempting with The Unarchiver 3.10.0 to extract a perfectly good zip archive located in Dropbox folder to some other folder in the local filesystem, the dialog is thrown:
"The Unarchiver needs to search for more parts of this archive, but does not have permissions to read the folder." then archive is declared corrupted which it isn't. Moving the archive to another folder in local filesystem solves the problem, extracts without any single question.

Upgraded to 3.10.1, the dialog is now thrown all the time. NOt possible to extract with The Unarchiver.

Screenshot, logs, zip archive in question

This is probably because you have multiple zip files in the same directory named, and so on. There is no way to distinguish whether these are multi-part zip files or individual zip files, unfortunately.

Hi Wakaba,

Great application! Curiosity question: I'm wondering… on the icon for The Unarchiver, there is a barcode on it: "57229 00132"; is there any significance to this number?


444 Name: !WAHa.06x36 : 2016-04-19 00:23 ID:KUkStYSQ [Del]


Good question! Adam Betts drew the icon, so he picked the number. I never thought to ask.

Is there any way to open z03 files? Or is that not possible yet?

446 Name: !WAHa.06x36 : 2016-05-06 00:42 ID:Heaven [Del]


z03 is just part of a split Zip file. You need to have all the parts and then open the .zip file.

After the update, I keep getting “there was a problem while reading the contents of the file…the archive file is incomplete” to all my archive files. Even the ones that were good on the pervious version.
It also does not que, is it gives me a “null” error.

I hope you find a fix for this and thank you for all your hard work.

449 Name: !WAHa.06x36 : 2016-05-19 10:59 ID:Heaven [Del]


There is a fix on the way for the first.

What do you mean exactly by the second?

450 Name: sad : 2016-05-19 11:06 ID:Pd8E2vuA [Del]

With the issue (there was a problem ...) I just clicked "Apply to all" and queued up the archived files (different files), usually they just start one after the other... but now this error comes up
(There was a problem while reading the contents of the file "null": The file could not be opened)

It could be related with first issue, so I will check it once again once the fix is applied.

Thank you again

451 Name: jenny : 2016-05-20 04:19 ID:hmP0WWLi [Del]


I'm having this problem too, glad that it's been reported and that you've got a fix.. any ETA?

452 Name: jenny : 2016-05-20 04:26 ID:hmP0WWLi [Del]

Is there a limit to how many archives can be queued up before the program crashes with an error? I find that if I queue up many (e.g. 12+), the program will come back with an error ("could not extract") which goes away if I re-queue the same file back. Is the limit based on free RAM?

453 Name: sad : 2016-05-20 10:55 ID:Pd8E2vuA [Del]


I just updated it, and it still have the same issue with queuing giving "Null" error as described in >>450

Hope it can be fixed

454 Name: !WAHa.06x36 : 2016-05-20 21:31 ID:Heaven [Del]


This should be fixed in the latest version, hopefully.


I can't reproduce it. Can you give an exact description of what you do to trigger it?

455 Name: !WAHa.06x36 : 2016-05-20 22:29 ID:Heaven [Del]

3.11.1 is now live on both the App Store and website, fixing the RAR error mentioned above.

456 Name: sad : 2016-05-21 09:39 ID:Pd8E2vuA [Del]

>>454 I have a file named (XYZ) which is in rar format (*.r00, *.r01. etc) and I start to extract it
then I add file (ABC) in rar format also.

After the program is done from file (XYZ) it gives the "null" error

It works fine for me. There must be something more to it. Does this happen with all RAR file or just those? Do you have another computer you can test on?

459 Name: sad : 2016-05-21 12:45 ID:Pd8E2vuA [Del]


I tried it on my laptop and it is working normally.
I tried it on rar files that never caused this issue and it had the same problem on my Mac.

seems the problem is affecting just my Mac

460 Name: sad : 2016-05-21 13:04 ID:Pd8E2vuA [Del]

I think I figured where the issue is

I placed few rar files in the desktop and it works normal in queue if the destination is the mac

but when i changed the destination to the external harddisk the program gives the "null" error after finishing the first file

same thing if I process it from the External HDD to the desktop.


from mac to mac, no isse
from mac to external, problem
from external to mac, problem

So sorry for the bad way to explain things

461 Name: !WAHa.06x36 : 2016-05-21 17:58 ID:KUkStYSQ [Del]


All right, I tried experimenting some more, and I did find some bugs. I am not sure if they are the exact same that you are hitting, so could you try testing this version for a bit to see if it works better, the same, or worse?

462 Name: sad : 2016-05-21 19:19 ID:Pd8E2vuA [Del]

I just tried this version
-went from external to external with no problem
-external to mac with no problem
-and mac to external with the same problem.

463 Name: !WAHa.06x36 : 2016-05-21 23:34 ID:KUkStYSQ [Del]


Gah, weird. Will have to investigate further.

Is your external drive formatted for Mac or Windows?

464 Name: sad : 2016-05-22 09:39 ID:Pd8E2vuA [Del]


its formatted for mac

465 Name: Blu : 2016-05-24 21:29 ID:kckPDzkE [Del]

Running v 3.11, DL'd from app store. Running OS X 10.11.5.
Keep getting error messages when attempting to extract multi-part rar files - "part x is incomplete" etc. Extracting to same folder as original files.

Doesn't occur with every set of files, but with most.

Files extract normally, and are complete, when using MacPar.


466 Name: !WAHa.06x36 : 2016-05-24 21:47 ID:Heaven [Del]

Is this 3.11.1 or 3.11?

467 Name: Blu : 2016-05-24 21:55 ID:kckPDzkE [Del]

3.11 (107)

468 Name: Blu : 2016-05-24 21:56 ID:kckPDzkE [Del]

App store reports it as up to date, FYI.

469 Name: !WAHa.06x36 : 2016-05-24 22:24 ID:Heaven [Del]


It's not, 3.11.1 is the latest, on the App Store too.

470 Name: Blu : 2016-05-24 22:45 ID:kckPDzkE [Del]

Deleted, and reinstalled 311.1. Thanks!

471 Name: Alex : 2016-06-24 06:29 ID:jKm8FT10 [Del]


The Unarchiver has trouble unzipping this file:

Whereas 7-Zip on Windows has no complaint about it.


472 Name: !WAHa.06x36 : 2016-06-24 11:47 ID:Q3uZRd0P [Del]


Confirmed. Will look into it.

473 Name: Nicole : 2016-06-29 19:55 ID:PYJx2yHm [Del]

I used to be able to open multiple archives at once and select one folder to extract them all to. Now, when I tell multiple archives to open, it asks me for each one, and it's annoying.

474 Name: Jon : 2016-08-08 08:17 ID:RVV7ltQ8 [Del]

Any plans to include .pae file extraction from the PowerArchiver software? Thanks!

475 Name: Henry : 2016-08-20 23:51 ID:UvM5RP4c [Del]

I downloaded to install in an old resurrected MacBook running 10.6.8 Snow Leopard.
The Unarchiver will not run. It quickly appears in the dock and disappears.
Reviewing the Console, it seems The Unarchiver is not recognized as a 64 Bit Intel compatible app.

Any suggestions for remedying this problem? Thanks!

476 Name: Edward : 2016-08-27 22:12 ID:4mt/++0z [Del]

Any news on a Windows binary update?

477 Name: Daniel : 2016-09-02 02:52 ID:Nngx60hb [Del]

On 3.11.1, still getting "incomplete part"-problem on multi-rar-files.

I've tried other apps, where the same files works flawlessly. But I'd feel really bad about abandoning The Unarchiver now after all these years :/

478 Name: Daniel : 2016-09-02 02:54 ID:Nngx60hb [Del]

On 3.11.1 and still getting "incomplete part"-problem with multi-rar-files, that work fines with other apps (but don't really want to abandon The Unarchiver :/ )

There should be a check box in the options to choose whether I want the unarchiver to autoupdate or not. Thanks.

Unarchiver will not open a zip file when I double click it now. It used to. Not it opens the preferences panel. How can I fix this?

483 Name: buzlink : 2017-03-31 17:25 ID:+zeT2c4C [Del]

What version number should I select to use on Mac OS X 10.6.8 Snow Leopard? I downloaded the version on the main page for older Macs and the program does not launch. I went through the archive of Unarchiver but wasnt sure what version number I should download. Thanks

484 Name: Anonymous : 2017-05-30 02:55 ID:d2XMzpQK [Del]

What a pity it doesn't works for archive .WPRESS :-/ I hop soon :)
Good job man anyway

485 Name: Grant : 2017-07-15 07:27 ID:K6TogFz9 [Del]

I downloaded a new version of the Unarchiver today, and the icons to the left of the file name for rar files show as generic.

I can get them to show the Unarchiver icon if I reduce the test size from 16 to 12. However, this is not a valid option, as reducing the view to a text size of 12 is hard for me to read, and also changes all of my epub preview icons to generic.

Well, it's official, Macpaw is taking over development on The Unarchiver, The Archive Browser, and even Xee!

I haven't been doing a great job of maintaining them lately, so I think it is for the best. Direct any future support questions to them.

I think I will shut down this board for the foreseeable future, as I have not really been keeping up with it either. If you need to reach me, you can do so here:
