s3uzip13.zip (30K)
This archive contains an EPOC binary for version 1.3 of Unzip
for the Series 3, plus some documentation.
This port is based on the Samuel H. Smith / Info-ZIP team source
code, as distributed in UNZIP50.ZIP in free_software/sources.
Version 1.3 adds support for unzipping from remote files across
the serial link using Mclink. This did not work in prior versions
due to failure of the CLIB stat() function across filesystems.
See below for an example of remote unzipping.
Version 1.3 *removes* support for the old (prior to Pkzip 2.0)
compression methods. This is to save space (and hence memory) and
reflects the fact that such archives are increasingly rare.
To use, you need version 1.1 of RUN.APP (included in the archive)
as the front-end for the UNZIP.IMG file. UnZip requires
considerable free memory to run, so its not suitable for
unzipping other than small files to the internal drive.
See the enclosed file RUN.DOC for brief notes on installing and
using the RUN utility. Here are some examples of the use of the
'Initial path' parameter with UnZip:
Command line: -l a:\transfer\myzip
Initial path:
Command line: -l myzip
Initial path: a:\transfer
Where only a listing of the archive contents is requested, the
two forms above are identical. Where an archive extraction is
specified however, the 'Initial path' parameter specifies the
directory to which the files archived should be extracted. For
example:
Command line: a:\transfer\myzip
Initial path: b:\
will cause the files in MYZIP.ZIP in the specified directory to
be extracted to the root directory of drive B. Note that the full
path name of the archive must be specified on the command line.
As of this version, remote files can be unzipped using Unzip and
Mclink. N.B. Slink should *not* be used as it is buggy in this
respect, and will fail for remote files >32K in length. An
example:
Command line: rem::f:\download\newstuff
Initial path: a:\
will extract the remote zipfile on the PC to the SSD in drive A
on the S3. This is the fastest way to move bulk data from PC to
S3.
