![]() ![]() There are many applications available on the Mac that are able to uncompress >4GB archives. Just drag it into your Applications, and you can do what you need to.Īll that said, the issue is unlikely to be file size, but rather the integrity of the archive. My point in stating this is that if you are having a failure with extraction with the standard ZIP dearchiver in MacOS (which is fair, since the original standard maximum is 4GB (original open source specification: )), you can use to bypass the 4GB limitation. ZIP files using WinZIP, 7-Zip, xzip, etc have a current maximum size of 16 exabytes, or if you are more comfortable with a better known file size, 16,000,000,000GB/ 16x10^9 GB, and has since June, 2015. Yes, some may have different screen setups in multiple auditoriums and need both formats, but I guess the majority only needs either version. I have never seen two trailers packed into one ZIP - makes no sense, especially with FLAT and SCOPE versions, since most cinemas usually show only one of these formats, and shouldn't be forced to download both. A suitable second hand Mac Mini or Mac Book would come out around 200-300US$ I guess. ![]() I think it's easy to get a hand on a Snow Leopard DVD and install it in a VM. When I get a couple of hours, I'll experiment with that. I do have a Mac OS CD, with which I experimented making a Hackintosh partition for one of my PCs a few years ago (it sorta worked, but kept freezing up on me). This latest one that's giving me a headache is for an Oscar-nominated movie ( A Man Called Ove), so it's not exactly some obscure student documentary about eggplant farming in Backofbeyondistan, destined only to appear at one or two arthouse fests.Ĭarsten - thanks I like the idea of Mac OS in a VM. My booths can't be the only ones on the planet that don't have a Mac in them, and so I'm surprised that the distributors of these big zipped trailers aren't experiencing more "I can't open this" complaints and investigating why. It's usually when you get the flat and scope versions in the same zip that they bust the 4GB barrier.įrank - agreed, and I'm surprised that this is happening as often as it does (about once every 4-6 weeks for me, at a guess). I think ATMOS trailers now start to break that barrier. Even the larger ones we download usually end around 3GB or so. There may be other issues around ZIP files larger than 4GB as well, not strictly related to an OS X archive function.įortunately, I think I have never seen a trailer of that size. It's a known problem indeed, and all I can suggest for now is to buy a cheap second hand Mac or run OS X in a VM to get a grip onto those files. Another form of extraction takes place then with no errors, the now unzipped DCP can be transferred with FTP or USB and ingested without issues. When I get to the DCP folder I left click and pull the folder out on the desktop. My workaround then is to double click on the zip archive and open it (WinRAR does that automatically). WinRAR throws an error (I can't remember exactly what right now, but it's something about something that is too big). I'm normally using WinRAR on Win 7, 8, 10 btw. I'm not sure it's the same issue but this is what I have experienced lately:Ībout 5% of downloaded trailers won't extract properly. I think modern versions of the Apple operating system are based on BSD Unix so tar and bzip2 should be readily available. There are numerous, arguably better, options for creating compressed archives other than zip. If they are sending you defective archives then I suggest the proper solution would be to tell them to stop doing that. ![]() ![]() I have had luck opening files that winzip will not. a third party zip program) that enables the contents of these big Mac zips to be extracted in either Windows or Linux (ideally in Ubuntu, but I'd be open to using another flavor of Linux live boot if that would do the job). We're being given more and more download links for trailer DCP zips that I can't open because of this, and I was wondering if anyone had stumbled across any fix or workaround (e.g. If you Google this, you'll find lots of stuff online about it, but this page summarizes the problem pretty well. This appears to be a well-known bug with the zip creator built in to Mac OS: zip files bigger than 4294967296 bytes cannot be opened on anything other than another Mac OS computer.
