Re: segmented zip files

I seem to have a problem here. On my Mac I have BetterZip set to Compatibility Mode. Let's say I have a file that is 350 MB's and it's a music file. I need to spit these files so that the max MB is 99. I then choose Zip (recommended). What comes out is 4 files, 3 of them at 99 MB's and the 4th a bit smaller. Each zip file has a numbered extension after the .zip (Ex: .001, .002, etc.). When I send any music files to a fellow collaborator who's on a PC (using WinRar or WinZip), they can't open the files at all. Kind of makes sense given that .00# is at the end of each file. Can this issue be fixed? I figured the Zip files could be unpacked on any computer or zip program.

Thanks in advance.

The sequential files created by BetterZip can indeed be unpacked on Windows, but unfortunately not with WinZip, at least not directly. You can either use 7-zip to unpack these zip files in one step or a program like HJSplit to first join the segments and later unzip the result with any archiver you like, e.g. WinZip. By the way, both tools mentioned are free.

Now isnt that a stupid thing. The whole idea in my opinion with a segmented zipfile is that anyone with mac or pc are able to open it. This is the main reason why betterzip now is useless to me. Id like to se this given feature in an update soon!

Sorry, but that's the way it is. There is no standard way to split zip files. BetterZip could either create segmented files the way WinZip does it or the way 7-zip and many other tools on the Mac, PC, or Windows do it. I chose latter, so I can tell any user that their clients can use a variety of (even free) tools on every platform. If this one point makes BetterZip useless for you, I am sorry, but I don't think you will find an alternative on the Mac.

Without being rude, I agree. There is some kind of built in unzip for windows, and I'd like to be able to create segmented files that can be unzipped by THAT version of unzip - while there might be a few different ways to segment and none of them standard, that would be the one that is standard for windows.

However since this is an old post, maybe I should ask, has this already been added?

I don't think, that the built-in archiver in Windows can extract segmented archives at all, but I haven't checked with the latest Windows version.
