Previewing incomplete .ZIPs, possible on an Amiga?

[AmigaMance]

Hi.
 I want to ask if it's possible to preview an incomplete zip, using an Amiga. When the zip consists of many small files, this is not a problem. I load it in Voodoo-x (or any other GUI frontend for XAD) and i dearchive the files which are contained in this incomplete archive. But what if the zip is consisted by only one big file?? Voodoo-x doesn't let me to dearchive the beginning of this big file. Same goes for the UnZip command. :-/
 With RARs, this isn't a problem! I only have to issue the option -kb (keep broken) in the unrar command and that big file gets partially extracted. Is there a way to do the same with ZIPs?

PS: I can use AOS3 and MOS.

ZIP format has the file structure (metadata) after the archived data. This explains why you can't access the file that is incomplete.

If i understood you correctly, you mean that the infos for each archived file, like its size etc, are attached at the END of it. That's bad... Zip format sucks. :-/  Thanks Piru.
