does OS4 have a .z01 solution?

Struck a distribution the other day released as a compressed zip?

i.e

file.zip
file.zip.z01
file.zip.z02
file.zip.z03

file.zip seems to be the end file since zip stores all the file names etc at the end of the file right? so for example I used cat file.zip.z01 file.zip.z02 file.zip.z03 file.zip > new.zip

(I did try other orders but this seemed the most logical)

any attempt to unzip it presents errors etc...

seems it's a new compression which current unzip revisions don't support...

I tried looking for a Open Source solution but didn't get very far... sent across to my modded xbox and that couldn't make any sense of it either...

any ideas? solutions?

thanks

@Slayer

btw the file is not password protected if that eliminates any troubleshooting suggestions...

I think I just need the right tool (software) for the job

@Slayer

Looks a bit familar. Have these files been downloaded from usenet ? Then IMHO the file.zip is a control file which refers to the .znn files. You should try to open the .zip file with WinRAR or WinZIP. If unpacking it is your only desire, that is. If you insist on doing it with the Amiga you should wait for an answer from someone with more knowledge than me.

@Slayer
Try joining them all together in order and then unzip?

@Slayer

On unix/linux:

If we have : File.zip, File.z01, File.z02, File.z03

#cat File.* > File-full.zip
#zip -F File-full.zip
#unzip File-full.zip

All those commands including "cat" have an Amiga port so it would be equal in AmigaOS

join should work in AmigaOS i suppose.

@ssolie, Fransexy, fryguy

Why don't you read the question before you answer ? He already tried this and it didn't work.

Bye,

@thomas

I thought that he forgot the "fix the archive of the overall zipped files" step after the join (zip -F files-full.zip)

Telling people to read harder doesn't help either.

@Fransexy

I haven't tried the -F switch but I think that's the answer and yes, the Amiga does have the same commands

@all

thanks for the nice response and support! I will post back if the procedure regarding -F doesn't work for the Amiga!

@Fransexy

argh... I tried it all ways... although looking promising with some combos it stills comes back to an invalid archive etc...

take this release for example... a small one... please feel free to examine it if you get a spare moment *hint* lol

http://rapidshare.com/files/113254804/055.Terror.Of.The.Autons.z05

I tried 055.Terror.Of.The.Autons.zip in front at the end and tried the archives in reverse order with 055.Terror.Of.The.Autons.zip at start and end...

-FF wasn't any help either...

the author of the releases suggests using powerarchiver to unzip them if there are any difficulties...

damn MS and it's endless formats!

Slayer mumbles and heads off to try and find an XBox powerarchiver?????

The main error was it always found the need to truncate the archive... the test release was around 730k once joined after various combos and unzip -F / -FF attempts the end archive was always between 180k and 290k... truncated somewhere in the process...

The only thing I haven't done which is simply cRazy... is jumble the .z0? archives up! lol

I seriously think we are looking at a new compression?

@Slayer

The procedure at the bottom of this page suggests exactly what you have done - join them together with the .zip at the end, then unarc them (I'd use the unzip command-line tool)

My research shows that these split files have been created with WinZip, so you might need to use that.

Also, new versions of WinZip have 64-bit support and better compression (PPMd and bzip2), so those might be tripping it up.

You may find p7zip can handle these.

@Chris

Thanks for the info Chris, read that same mac page earlier on and have tried p7zip from that exact source also...

guess I'm stuck for the moment... no matter :D
