Description:

xzip 0.10

xzip is a FUSE file system for deduplicating zip files which share zipped
contents.
To install use:
$ pip install xzip

or

$ easy_install xzip
xzip provides three executables zipexplode, zipanalyze, and
mount.xzip which will “explode” a zip, analyze a zip file, and mount
exploded zips respectively.
The file structure for an exploded zip is the following:
$ zipexplode path/to/zip/name-of-zip.zip
$ tree .
.
├── data
│   ├── <sha1-data-file1>
│   ├── <sha1-data-file2>
│   ├── ...
│   └── <sha1-data-filen>
└── meta
   ├── name-of-zip.zip.dir
   ├── name-of-zip.zip.jump
   └── name-of-zip.zip.stream
The file structure would be mounted by:
$ mount.xzip . path/to/mount/point
$ ls path/to/mount/point
name-of-zip.zip
Data files may be shared between any number of exploded zips files, and the
meta tuple (*.dir, *.jump, *.stream) describe the original zip
file.
zipexplode accepts two options --directory and --depth to modify
where it creates the data and meta directories and how many levels deep
the data directory should be. zipexplode can explode multiple zip files
at once, and additional help is provided with the --help option.
zipanalyze simply prints out the sha1 of different segments of the original
zip file. This script was used to determine what could be deduplicated, and
what needed to be stored per zip file. This executable is mainly of historical
use.
mount.xzip will mount the directory structure described above, and needs to
be supplied with matching directory and --depth arguments to when
zipexplode was called. Additional arguments --debug, --foreground,
and --single-threaded are passed to FUSE and control underlying
functionality. For more information see the --help for mount.xzip.
(mount.xzip also takes -o style options)
Note: At this time xzip is not zip64 safe
