Decompressing z01 and encrypted files

Hey i'm having trouble decompressing this multi part (.zip and .z01-.z03) files becuase i eitehr get an issue with the file not beinga supported archive or something along those lines usually.
ive tried about 6 different decompression applications without much luck. i have a password for the files but havent been prompted to use it, heh.
well thanks
 
no help?
surely somones opened one of those that takes 4 zip files and has a password over it all.
wrong forum? someone help <33
 
UnrarX will uncompress them, just point it to the first part.

As for the password, dictionary attack is the best bet, there's no simple way round it other than letting a program "guess" the password.

IMO don't download warez. 😛
 
Sounds like the original content was zipped, password protected and split into .01, .02, etc. chunks. Use K-werkx Faste File Joiner for the chunks - still works like a charm.

Once the file is joined, open the resulting full zip and enter pass when prompted.

this seems to be workignt he best of everything, however its asking for a file extension similar to ".001" whereas mine end with .z01 or whatever.
should i just rename the extension or what?
 
renaming the .z01 etc to .001 etc and linking them created a file without an extension. thast why i gave up 😛
 
How to join and expand such files like the following ones?

File.z01
File.z02
File.zip

No way with StuffIt Expander, Unrar, Split & Concat, MacHacha or MacPar Deluxe.
 
Decompressing .z01 and encrypted files

The following procedure has worked for me:

1. Change all the .z01, .z02, etc. file extensions to .001, .002, etc.

2. Change the file extension of the .zip file to .00X (X= the last numeric file extension from the .001, .002, etc. files + 1)

3. Join all segments with "MacHacha".

4. Change the name of the file produced by "MacHacha" by adding the extension .zip .

5. Unzip the this new zip file with "The Unarchiver".

6. Submit correct password if necessary to unzip.

Let me know if this works for you...

This method works!!! BUT remember from step 2 that the file that already has the extension .zip is the last file out of how many your joining (like for three files its the file with the name you give it ending in .003 and .005 for five files). Also make sure you use unarchiver! Stuffit Expander doesnt work!!!

BTW another splitter/combiner that i use is split and concat (i find this quite useful to join hjsplit files on macs)

Btw just signed up to this forum to confirm this for anyone, you probably wont see me post here again. Hope i helped, took hours for me to realise i had the answer already, i was just doing it wrong 😀😀😀😀😀
 
Found a way to Extract .z01 stuff only using ZipIt

Here is a way that I stumbled upon after reading the above. It does NOT require re-naming, lots of programs, etc. Just ZipIt for the Mac.
First: open the .zip file with ZipIt. The file will open and you should see the (uncompressed) file you are trying to "get" (e.g. "ThisAwesomeMovie.avi"). Double-click that file-name (to signify that you wish to start extracting it). The program will ask "where do you want to save" -- YOU MUST choose somewhere OTHER THAN where the parts are located. Then it will ask for the first part. Choose the .z01 file (within the file-open dialog, you may have to select "show all files" instead of "show valid files"). Go through selecting them one at a time when asked. At the end it will ask for the part N+1 (for example, "part 7") -- that is actually the ".zip" file which you started with!! And, all is good...🙂
 
found a way without having to rename files to open z01 type files

Every time I use Machacha to join the files it always misses the last file out. I had a file of 9 segments and it will only join 8!

Here is what I did:

for arguements sake your file is z01, z02, z03, z04, z05 and zip.

Open Split and Concat. Select concat. Select the .zip file. Now it will join all the files together.

Once done, add a .zip extension to the new file that has been created.

Now open this file with "The Unarchiver"

This worked for me without having to rename any files.

These babies are a major pain in the ass to work with, but I will say that your method was the easiest and most intuitive for me to work with. Just joined up to say thanks for the help......

You totally nailed it, Jameseye!

Nothing else worked for me (and I tried the other programs suggested here to no avail) until I followed your detailed instructions using ZipIt; perfect!

Thanks so much for your help! 🙂
 
EASIEST SOLUTION (3 Really Quick Steps Explained in Detail)

STEP 1
Download the free Unarchiver application for Mac. Available from the Apple website at the following URL:

http://www.apple.com/downloads/macosx/system_disk_utilities/theunarchiver.html

STEP 2
Rename the file extensions on each ".zXX" file to the ".XXX" extension as follows:

.z01 to .001, .z02 to .002, etc. (if the number of files is greater than 9, begin using the next available "0" to continue numbering, ex: .z10 to .010)

Each time you change the extension, a pop-up message will ask if you actually want to change the extension. Select "Use .XXX."

There will be a .zip file as well. Rename it to the ".XXX" format as follows:

If the last ".zXX" file is, let's say, .z06, and you have changed its extension to .006, then the .zip file will become .007 (it is treated like the next sequential file). The .zip file will always become the last number in the sequence.

STEP 3
Select all of the newly changed files (now formatted as .XXX) and select "Open with Unarchiver" by right (secondary) clicking on one of the selected files and choosing the option from the pop-up menu.

The Unarchiver application will open and begin processing the file. Once complete, the application will automatically close and the uncompressed/no-longer-segmented file will appear in the same location as the .XXX files.

Hope this helps 🙂
 
mhw323 and JamesEye solutions.... both good

hi mhw323. This is JamesEye (I posted an earlier solution).
Your solution looks good too.
Although, I am not sure if it really is EASIER than the one I posted.
Personally, I find all the rename-ing (with responses to "Are you sure you want to rename...") a bit tiresome.... but, perhaps this is just personal preference.
Anyway, thanks for sharing.
