The asterisk is a wildcard in Linux, which expands to any file or folder matching the pattern. Next, we run gzip with a single argument: gzip /. First, we’ll change back to the top-level testdir: cd /testdir. Archive Utility will create and read it's own 10GB archives without problems, but can't unpack the infozip archive either. To compress multiple files at once, we can use gzip with wildcard expansion. I tried with both the builtin unzip (5.52, dated 28 February 2005) and the latest from fink (6.00, dated 20 April 2009). Infozip will create 10 GB archives, but not unzip them. So perhaps the files created by zip64file are incompatible with infozip on MacOSX? The zip64file docs specifically say they were targeting compatibility with PKZip: On MacOSX 10.6, I could create and read 10GB archives with zip64file, but they weren't readable with the builtin infozip or Archive Utility. The 50GB archive works fine with GNU tar on the same system. Though I've had problems with a larger archive (50GB) created by zip64file (which I haven't been able to get working with any zip implementation). My standard test was creating an archive containing a 10GB file and a handful of smaller files, and I was able to read them with zip64file and with infozip on linux. My main test was using zip64file ( ) to generate zip64 zip files. It to them? Then do not be too eager to deal out death in judgement." Google Code jtar ( ): haven't actually tried this, but there are no docs and the code looks like it's using the old 11-digit octal (7.99GB) limit.ĭoes anybody have experience working with tar/zip archives larger than 8GB in Java? Should I just fall back on command line tools with better large file support? ICE JTar ( ): accepts files larger than 8GB, but produces archives incompatible with GNU tar. Although the zip and tar formats both support files larger than 8GB, and command-line tools support that, I haven't been able to generate archives that large with the Java libraries I've found:Īpache Commons Compress ( ): 7.99GB for tar, inherits 4GB limit for zip. This will take some time, depending on the size of the file.Īfter this completes, you will see the separate files in the same location as the original file.I've been trying to generate BagIt packages of our digital objects, wrapped in either tar or zip archives to make it easier to move them around over HTTP. You will see a progress window displaying the status. zip extension at the end of the file name. You can also change the name in the Archive: section, be sure to keep the. Then in the Split to volumes, bytes section, enter or choose a size from the drop down menu.
