Data unzipping issue

Hej,

I am trying to extract the images from the zipped files but i am getting error. I am on a linux machine and i use the below commands to extract the contents from the multipart zip files. Let say we are in Part1, so i run the following commands:

• cat ULS23_Part1.z* > combined_ULS23.zip
• unzip combined_ULS23.zip

While, running the second command, it throws an error as follows:

"Archive: combined_ULS23.zip error: End-of-centdir-64 signature not where expected (prepended bytes?) (attempting to process anyway) warning [combined_ULS23.zip]: zipfile claims to be last disk of a multi-part archive; attempting to process anyway, assuming all parts have been concatenated together in order. Expect "errors" and warnings...true multi-part support doesn't exist yet (coming soon). warning [combined_ULS23.zip]: 12884901888 extra bytes at beginning or within zipfile (attempting to process anyway) file #1: bad zipfile offset (local header sig): 12884901892 (attempting to re-compensate) creating: ULS23/ error: invalid zip file with overlapped components (possible zip bomb)"

Could you please let me know how can i unzip the files properly? Can you also share some reference links for the same?

Thank you.

I'm using '7z x ULS23_Part1.zip' command which seem to work well. This way there's no need to merge the different parts together, 7z handles it all automatically. Hope it works for you as well.
