Zip files won't unzip

I have downloaded a couple of zip files, and am trying to use the default Archive utility to unzip them. Instead of opening the files within the zipped folder I'm getting a .cpgz folder with the exact same name... then when I try to open that file it makes a duplicate .zip folder and I just go in circles.
Any idea what the **** is going on?

Go to http://www.stuffit.com/mac-expander.html and download the free Stuffit Expander. Once it's on your machine, drop a zip file onto it, and see if it expands. That will eliminate some possible broken items.

Zip file won't unZip!!!

hello,
I made an archive of some files using the finders "Create Archive" function. Now I cannot get the file to unzip.
Just when the files appears to finish unzipping I get the following message.
Unable to unarchive "name of File" into HD 250.
(Error 1 -Operation not permitted)
What can I do to unzip this file? HELP!!!
Thanks

I use "The Unarchiver" for a couple of months now. Works better than the built in app. Maybe you give it a try:

Zip archive won't unzip

Hi all!
I made an archive of a rather large file full of movies, then I stupidly deleted the original, because I thought "hey, I have an archive of it." Now the file will not unarchive. It goes through every file in the archive, then gets to the end and an error pops up. It says:
Unable to unarchive "Movies.zip" into "External HD".
(Error 1 - Operation not permitted.)
So I tried to unzip the file from the terminal, and it gave me this:
dlvs-computer:~/Desktop DLV$ unzip Movies.zip
Archive: Movies.zip
End-of-central-directory signature not found. Either this file is not
a zipfile, or it constitutes one disk of a multi-part archive. In the
latter case the central directory and zipfile comment will be found on
the last disk(s) of this archive.
unzip: cannot find zipfile directory in one of Movies.zip or
Movies.zip.zip, and cannot find Movies.zip.ZIP, period.
This doesn't make much sense to me. Please help! I want this file back (and I will never make another zip file in my life, I swear to god).

you can try to change utility to open the archive.

Mac zip files won't open in Windows PC

I have been right clicking and compressing raw .mov video files to send from the UK to Australia via wetransfer. I am using a Macbook Pro with Mountain Lion. Each set of zipped files is between 3GB - 8GB in size and they (compress) and zip and send fine. But my client is on a Windows PC and only now tells me they are having problems opening the "zip" files I have sent them. They get the message that the zip is "invalid". Any ideas what can be wrong here? I tested them on my Mac by reopening and they work file.
Many thanks in advance.

Step one would be to try them on a local windoze box. That should give you some indication of what might be wrong. Alternatively, try the Terminal command gzip. Read about it by typing in man gzip in a Terminal window and then pressing the return key.

Zip file won't open

I have lost a few photos transfering files from the macbook g3 iphoto to the aluminum macbook and iphoto 8.0.4. The info (name, size, date) are visible but no photo. I was short of space in the ibook so I backed up iphoto on a thumb drive and 'archived it' into a .zip file. This file will not open in the macbook. (Error 1 operation not allowed). The file is 516 mb zipped. The ibook has 1.75gb available on 10 gb HD but part way thru the unarchiving process it announces the startup disc is almost full and then the ibook screen goes black. Any idea how to get at this data.

Some of the issues you relate to may have something to do with
the differences in iPhoto versions and the possibility of their being
not so directly compatible when moving images the way have did.
The compressed file should be transferred unopened to a larger
external hard disk drive or somewhere the file can be put on to
a DVD or other media, should the lack of free space in which
to open & view the compressed file be a problem in a hard drive.
Although it may not help the situation, there also are other
unarchiver software types out there which could also open
the compressed file; but only if there is adequate space in
the location (or another location can be selected) to do so.
The Unarchiver - an alternative to BOMArchiveHelper. app:
http://www.apple.com/downloads/macosx/systemdiskutilities/theunarchiver.html
The problem sounds more complex, perhaps, than it is;
or maybe it really is complex due to how you have made
this archive of the iPhoto image library from the older
iBook (? you say Macbook G3) and its iPhoto version.
Accessing the jpg images should be relatively easy if they
are not messed up in some odd copy of the actual iPhoto
version from the older OS. This is where your description
is a bit lost on me. There is a way to make backups and
also copies of the iPhoto libraries themselves; but there
have been some issues (supposedly addressed) in how
older iPhoto images were seen - or not, by the newer
version of iPhoto.
If there is not enough free space in a computer to open
a large compressed file (and run the apps, swap files
and other Virtual Memory the computer needs to work)
then the file should be opened elsewhere.
A computer's hard disk drive, where the system resides,
should never be more than 80% full. Mine are 50% full.
Backups to DVDs of images, music and other works in
progress could be made to safeguard them. Some types
of libraries may not be the best way to do this; in the case
of my own images, I do not use iPhoto. My jpg and other
images are saved by date into folders, by year; any edits
are saved in their own folder in the date folder, direct from
the camera into a new folder on the desktop. One of my
favorite apps is ToyViewer for image editing, a freeware.
{My edits also are not very complex since I try to duplicate
my skills as a film photographer, in the new digital world.
Photoshop & other alterations take away from experience.
If I were to take 10 hours painting my images fantastic, I
could hardly justify not just taking up fine art. I can do it.
Simple resizings, rotations and rename images= editing.}
Please explain in more detail about the way the image in
the older computer were archived, and where; and what
they were a part of. I don't know if I understand correctly.
PS: If the image file you compressed (assuming it is only
images and not part of the older iPhoto app) you could
try to see if using FireWire target disk mode could be used
to get the files direct from the iBook hard drive into another
computer; not sure what MacBook you have, some new
ones lost the FireWire ports. The compressed file could
be moved from iBook to another computer & opened there.
Good luck & happy computing!

My Zip files aren't unzipping

I receive PDF-zipped files for work via email attachments, but when I double click on them, the window disappears (a brief flash of a message saying the file is being "archived" flashes, but then nothing.) When I go to my user>library>maildownloads, and click on the file there, the same thing happens.
I tried selecting "open with" to open the PDF files Adobe, but then I get a message saying that the .zip is not a supported file type.
Help!!

As an alternative Download and open with "Stuff it expander" http://www.stuffit.com/
Right click on your zip file and "open with."
The default ArchiveUtility for opening ZIP files seems to be a little buggy in OS X 10.8.2.

PDFs, ZIP files won't launch or download when clicked.

When I click on a link to a pdf or zip file in Safari, I'm no longer able to view the pdf in my browser with the Preview plugin, nor am I able to download the pdf (or zip file.) On clicking, a new blank window launches, but that's it. Nothing downloads or loads.
I've tried reinstalling Safari, and that doesn't work. Anyone have any thoughts?
p.s. I want to view pdfs with Preview ideally, not Acrobat. Acrobat is way too sluggish.

If you have Adobe Reader installed, there has to be a plugin installed in that folder, unless you deleted it at some point. It may be called AdobePDFViewer.plugin, and it can only be in that director path that I gave you: HD/Library/Internet Plug-Ins. Check to be sure it's not there.
Once you're sure it's not there and Adobe Reader was deleted, quit Safari if it's running, paste this command in Terminal, press Enter, then quit Terminal:
defaults write com.apple.Safari WebKitOmitPDFSupport -bool False
Restart Safari and try dragging a PDF file from your Desktop or elsewhere on your Mac into an open window and it should display without any problem.

.001 Zip file won't decompress

I'm having problems downloading zip files. They're actually zip files broken into parts - and inevitably the first of them will not decompress. The system goes through the whole download, and then just freeze up on the Decompression stage. Sometimes it will try to decompress as long as I am willing to let it try and other times I get a decompression failed message. This only happens with the file with a .001 associated with it...
Anybody have any idea why this is happening?

Are you using Stuffit Expander?

Stuffit & zip files won't unarchive completely

Here's another issue I'm having (I've got time today, so I figure I'll get them all out there:)
I recieved a sit file from a client through email (I'm using Mail). When I tried to unstuff it, it wouldn't unarchive completely. The stuffit progress bar got about 3/4 full, then stopped & estimated time started going up to like 272875 hours.
I let it continue for a while (about an hour...it was only a 1mb file btw) but eventually had to force quit stuffit, although it never actually froze or crashed. Then I noticed that the file it created on my desktop had some, but not all, of the items inside. This file was reading a size of 3 gb!!!
So, I had the client re-stuff & re-send.
Same issue.
I tried opening stuffit expander & dropping the file on to the icon and tried file / expand in the menu.
No dice.
I tried opening w/ older version of stuffit deluxe 6.
Nope. File type not supported.
I even asked the client to try zipping the file using osx's built-in functionality, but then I got "Unable to unarchive (Error - 1 Operation not permitted)" from Archive Utility.
I just don't know if it's a problem w/ stuffit, or if something's getting weird throught the file transfer, or it's if it's an os thing. Anyone out there hear of something like this happening before?
I'm running osx 10.4.6 & stuffit expander 10.0.2.
Client is running osx 10.3.9 & stuffit 7.
Thanks:)

Can you use the command-line "unzip" tool to look at the archive's contents (maybe there are filenames that have weird characters or are otherwise troublesome on some OS X disks) and do an integrity check? If the archive is called Archive.zip in your home directory, use the command unzip -lt Archive.zip in a Terminal.app window.
Can you use that same tool to expand the archive? unzip -v Archive.zip (-v will give some information about each file as it goes, so you might be able to see at what point it has trouble).

How to read/unzip a specific file within a zip file

Hi,
I have a file within a zip file that contains a timestamp - I want to read this timestamp and then create a destination directory for the remaining zip files to be unzipped into. Since I know the name of the file with the timestamp in it I thought I could create a zipfile and use getEntry to get the entry but then other than getting the size and name of the file I can't do much more with it like read it unless I use a stream (zipinputstream) instead of a file (zipfile) - do I have this right?
Does this mean to get the content I would have to loop through possibly all the files using the stream until I come across the one I want - then get the timestamp and loop through them all again to write them to the destination directory? Or am I reading this wrong - seems a bit round about.
Any suggestions would be greatly appreciated.
Thanks

this works though - and you don't have to loop through all the files - just use the ZipFile:
ZipEntry ze = zipfile.getEntry("path/to/file");
BufferedReader br = new BufferedReader(new InputStreamReader(zf.getInputStream(ze)));
line = br.readLine;Thanks!

How do you stop automatic unzipping of .zip files

When downloading a flashable .zip file Yosemite automatically unzips it. How do you prevent this?

We've been experimenting with this today.
You can avoid getting the file by turning off the autodownload in the IM settings. The sender sees the file transfer, but it's not going to your machine. To get the file, you then need to click on it. It IS still going to Skype's servers though waiting to be retrieved and that is a worry.
A link is generated to retrieve the file. The link is sharable with anyone who is a skype subscriber.
Are these files ever deleted?
This makes me worry about the security all files sent via skype since it is the way-station and holder of these files. For instance, is it possible for a computer to check the randomly assigned numbers until they find all sorts of things?
We are using the 7 series versions.

How do I open a pw protected zip file?

This question appears to be different from similar questions asked because I HAVE the password. I really don't want to download extra safe-cracker's-anonymous software to hack into it. The file just never gives me the option of entering it. I have the zip file, I double-click on it, it gives me an error message. I right-click on it but no options there either. How do I open it such that it gives me a chance to unlock it?
Appreciate the help. (and yeah, I have no idea if I'm in the right community - sorry about that if I'm in the wrong place)

The zip file format is not a nice, standardized format. You could have a weird zip file that is technically not bad, but isn't supported by the built-in software on Mac OS X. In some cases, when zip files won't open, I've had success opening them with The Unarchiver, which is available both in the App Store and outside it:
https://itunes.apple.com/us/app/the-unarchiver/id425424353?mt=12
http://unarchiver.c3.cx
(I don't know if there's a difference in functionality between the two... there could be, but if there is, I am not aware of it.)
It's also possible the zip file is corrupted, and won't be openable by anything.

Password Protected Zip Files

i have recieved a number of password protected zip files which the unzip utility in osx leopard will not open. (i have the correct password).
i've downloaded a couple of smallish utilities from the download area but they don't seem to be able to accept a password either.
would someone be kind enough to point me towards a download (hopefully on the apple site) which can accept a password to open a zip file.
thanks to all.
ps-in the interests of futility i did try my unrarx application on an off chance it would work. it didn't.

Here's some you could try. The first two links are to zip utilities for OS X. I can't tell you if they'll do what you need, I just looked for zip programs that work in OS X.
The third link is for the free Stuffit Expander. The last link is the results for "zip" at VersionTracker. You'll just have to try a bunch of them to find one that hopefully works.
