Join Zip files?

Photek · 10-29-2006, 03:42 PM

One of the architects (that uses a PC) has emailed me a large file split into 3 zip chunks, file 1 is called Plan.zip, and the other parts have numbers after them. Does anyone know of any utilities to unzip and join them on the Mac? If I try Stuffit I just get errors.

ThreeBKK · 10-29-2006, 04:16 PM

Are you using Stuffit Deluxe or Standard?

vanakaru · 10-29-2006, 04:26 PM

Try MacHacha or Split & Concat.Put the files into same folder and open the first one Plan.zip. I hope it works, but I am not sure about split done in PC.

Have you tried simply double-clicking on the first .zip file in Finder?
Assuming that you don't have Stuffit configured to take over handling of ZIP files (if you do, then maybe temporarily remove Stuffit) the Finder's internal unzipping (BOMArchiveHandler) should take over and I'm hoping that will work.

Otherwise, you probably can just unzip each part separately and then concatenate the results to recreate the original file.
To concatenate files on the command-line (in Terminal):
cat file1 file2 file3 > combined_file

The 'unzip' man page also seems to suggest that you could concatenate the .zip files to get a combined_zip_file and then use 'zip -F' to fix it up before using 'unzip' on it to extract the original file.

cat file1.zip file2.zip file3.zip > combined_zip_file
zip -F combined_zip_file.zip
unzip combined_zip_file.zip

Interesting. I’ve experienced a number of instances where BOMArchiveHandler would unzip a file just fine – whereas Stufitt (Standard) would crash before completing the task.

Is this app more reliable, or is that generalizing too far?

If memory serves, my system wasn't able to open .zip files without Stuffit. I had to find and download a free version of the app. by jumping through a bunch of hoops on Allume's site. Then again, the package that was giving me trouble could have been another archive format other than .zip.

ThreeBKK · 10-29-2006, 10:16 PM

Yes, bad memory. I just successfully opened a .zip file using only the BOMArchive app. I must've been thinking about .sit or .bin.

Photek · 10-30-2006, 03:43 AM

will try some of the suggested apps and post back.

dude...

I have tried finderzipthing, Stuffit and even HJSplit with no joy.

Hi y'all,

I came across a problem similar to photek's and read through the comments here looking for a resolution. Since there was no conclusion, I thought I'd let people know my results.

Hayne's suggestion worked perfectly:

open up terminal
navigate to the folder with the files in it
type in: cat file1.zip file2.zip.002 file3.zip.003 > combined_zip_file.zip
then you just double click the resulting zip file per normal

Thanks for the suggestion. This forum's gold

I had the same problem with multiple .rar files.
Stuffit would just open the first .rar then burp.
I had to unrar on a pc with winrar then burn the
file to cd to xfer to the mac.

Might be a coincidence, but a recently updated app on the homepage of MacUpdate:

	MacHacha is a utility to split and join files using various common cross-platform formats (Mac, Unix, Windows), such as hjsplit, hacha, fastsplit or winsplit. Since version 1.1, also supports joining-uncompressing RAR files.

	If you'd like transportate a 5MB document in a floppy disk to your home, or fit a 400MB archive in two ZIP discs, or even move a 7GB film to a computer with a DVD burner and you only have a single CD-RW, this is your tool. If you wish share a 6MB document with your PC-friends over the internet and you can only put up online chunks of 1MB because of your ISP restrictions, this is your tool. MacHacha will do a simple job: split archives into smaller parts and join them when requested.

That can also be shortened up like this:

Code:

cat file[1-3].zip.00[1-3] > combined.zip

That's really useful for files in many pieces. Although hjsplit adds zeros in front of split files, so if it's in more than 9 or 10 parts, the command might have to be run twice:

Code:

(cat file.zip.00[1-9] && cat file.zip.0[10-94]) > combined.zip

When I try to download zip files, in many cases the first file comes out .wmv.zip.001.zip, and the others wmv.zip.002, .wmv.zip.003, etc. How can I get ride of the additional "zip" on the first file to make it .wmv.zip.001? I've tried deleting it, but it just reverts to the original form. THANKS.

trevor · 10-25-2007, 06:49 PM

After you change the name of the file in the Finder, you'll get a message saying

'Are you sure you want to change the extension from ".zip" to ".001"?
If you make this change, your document may open in a different application.'

You have to click the button marked "Use .001". The default button is "Keep .zip", which will make the filename revert. If you click the "Use .001" button, it will stay as you've changed it.
