It’s fairly safe to assume that the file parts just need to be concatenated together.
The easiest way to do this is within 7-Zip – navigate to the folder in the 7-Zip file manager, right-click on the first file in the sequence, and select “Combine Files…” from the context menu.
It can also be easily done on the command line.
copy /B input.z* output.zip
cat input.z* > output.zip
Usually there is one *.zip in the set and a couple of *.z??.
If you open the *.zip the others are unziped as well as long as they are in the same
If this does not work try what therefromhere
said, or if you are on windows:
copy /B yourfile.z00 + yourfile.z01 + yourfile.z02 yourfile.zip
Have you tried to unzip all the files? Usually, one have to unzip just one (the first or the last).
Maybe, if you change the extesion of the
.zip, will be able to unzip all.
Usually when i receive split files , i unzip the first file only.
Doing so gave me the complete file, I used 7-zip
I had difficulty with two files I received as xx.zip and xx.z01. I simply did:
cat xx.01 xx.zip > yy.zip
Gave a few warnings, but did the job. This was on Ubuntu Precise.
My guess is that they were just split directly, with no extra information, so you should be able to just concatenate them and end up with a full zip file. This thread has some links to tools that can concatenate files.
Solution Using 7z
- Open the folder where the split folders are stored. In my case they were 16 files named from *.7z.001 to *.7z.016
- Right-click on the first of the folders and left click to select the “Extract To” suggested folder name proposed automatically by 7z.
- 7z then creates a new uncompressed folder inside the same folder and starts unzipping and combining all of them.
I created a new folder, drag the split files into that folder. Highlight all files, select Extract. This will create a new sup-folder where your combined files will be located. Used 7-zip.
Open your 7-zip file manager and and navigate to where the parts are, you can then highlight, right click and extract here or wherever you want the end file to be located.
Plain combining 2 individual archives into one will not work. In fact I just tried that on zip, bzip2 and xz archives. All reported the outcome archive to be invalid. It might work with proper multi-part archives though.
