Re: [Flashcoders] Zipping in AS3
Hey Claus, one of the reasons I can't use it is because of its inability to work with a .zip file created on Mac OSX. The other reason, is that I've attempted to use it to write out a .zip file, and I can't get it to produce a valid .zip file. I've even tried loading in a .zip, and then saving it out directly, and that doesn't seem to work. I have only tested this with AIR, so I assume I don't need to be testing this with a .zip file that contains the Adler32 checksum. Do you have a working example of this working with FZip? If so, I'd love to take a look at it. Thanks! It is true that FZip can't read ZIPs created with the MAC OS X Archive utility, or any ZIP that makes us of data descriptors. For your other problem, i created a very simple Flex AIR app that tests roundtripping (creates a ZIP and loads it back in): http://codeazur.com.br/lab/fzip/examples/RoundTrip.mxml Works here.. And yes, in AIR the Adler32 limitation doesn't apply, so you should be able to load any ZIP (minus those that make use of data descriptors). You only need the injection hack if you use FZip in the plugin (and if i recall right Flash Player 10 is going to fix that but i didn't find the time to check).

AS3 Zip from nochump avoids the alder32 issue by implementing the deflate() mechanism in software. http://nochump.com/blog/?p=15 It's not as fast as the native bytearray methods though (which only works in AIR anyway). The only thing you might have to deal with is re-writing the parsing routines so that you don't get a script timeout error on large zip archives. I had to do this recently for a project. - jon ___ Flashcoders mailing list Flashcoders@chattyfig.figleaf.com http://chattyfig.figleaf.com/mailman/listinfo/flashcoders
