Further zip tools of possible interest:

Although not discussed here, it should be mentioned that the original Info-ZIP homepage provides further tools, e.g. for the creation of self-extracting zips, gzip and zipsplit, and of course zip/unzip binaries for many other operating systems.

Example for searching through zip file contents:

searches all .java files within eclipse.zip for lines with the words «public» AND «class».
Note that zzfind can also search files in a zip within a zip (nested zips).

How to list nested zip file contents (zips or jars within zips):

For example, if you download the Eclipse SDK and type you get a listing of less than 2000 files, listing also .jar file names. But how can you also list what is inside the .jar files, without the need to extract everything first?

Download Swiss File Knife Base, then type: This will produce a listing of all files, no matter how deeply nested — in total nearly 70000 lines that can be very long, for example:

The above is the text of a single line (filename), split into 4 lines here for better reading.

As you can see, there is a .class file in a .jar within another .jar within the .zip.

Limitations: SFK may not be able to process very large zip files, zip files with an unusual compression method, or 64 bit zip files. Type sfk help xe to list all limitations.

How to list the contents of all .zip files in all subdirectories:

In the example above, we listed the content of a single zip file. But sfk can also list the contents of all .zip, .jar, .ear, .war and .aar files in a directory tree. type: and get the most comprehensive listing of all files, all .zip (.jar etc) file contents
and even zip contents embedded within other zips.

Flexible file selection for zipping, using sfk:

If you don’t want to zip all files of a directory tree, but for example

• files that changed today, or since a date
• files with a specific file extension
• all files except those in subdirectories \save\ and \tmp\
• files that are different compared to another directory

then you have to prepare a file list with the swiss file knife, and send this to the zip tool through zip’s option -@ (read file list from standard input).

example: zipping files changed today

example: including/excluding by filename

example: comparing directories

we have two directory trees, «docs» and «docs-old». the latter one is a copy of docs, made some days ago. meanwhile, there have been changes in «docs». but what changes?

so let’s collect all these differences into a .zip. notice that zip would be irritated by the [add] and [dif] prefixes in each line, therefore we have to add sfk option -pure:

now let’s send this to zip:

NTFS and ZIP — execution prevention problem:

i experienced one small problem when using the command-line (un)zip together with NTFS file systems; in short terms, after unzipping «.msi» files, I was unable to install software from these files. windows complained that access to the files was not possible or denied (due to some «execution prevention» mechanism introducted with XP SP2). this was probably because i zipped those files from a FAT partition (maybe even with an older zip tool) and then unzipped them on NTFS. the solution was to copy the files to a partition with FAT(32) file system, e.g. an USB stick, and then to run the installer from there.

NTFS and ZIP — filetime jumps:

another issue concerns filetimes, especially when zipping/unzipping accross FAT and NTFS partitions. in short terms, if you zip files from a FAT partition, then unpack this .zip on an NTFS partition, you always have to expect that the filetimes may be changed globally by a few hours. This is not at all a bug in the zip tool — it’s due to the way that NTFS manages filetimes internally. in case you’re irritated by this, try the following: 1) remember the filetimes in some directory on an NTFS partition. 2) change the date of your system from summer to winter time, or vice versa 3) have a look again at the filetimes and be shocked: all file times have jumped by one hour! so this is not a zip-specific problem, but it may show up when you compare times listed in a .zip file with those of the files actually created.

UnZip for Windows

UnZip: list, test and extract compressed files in a ZIP archive

Version

Description

UnZip is an extraction utility for archives compressed in .zip format (also called «zipfiles»). Although highly compatible both with PKWARE’s PKZIP and PKUNZIP utilities for MS-DOS and with Info-ZIP’s own Zip program, our primary objectives have been portability and non-MSDOS functionality.

UnZip will list, test, or extract files from a .zip archive, commonly found on MS-DOS systems. The default behavior (with no options) is to extract into the current directory (and subdirectories below it) all files from the specified zipfile. A companion program, Zip, creates .zip archives; both programs are compatible with archives created by PKZIP and PKUNZIP for MS-DOS, but in many cases the program options or default behaviors differ. (For example, UnZip recreates the stored directory structure by default; PKUNZIP unpacks all files in the current directory by default.)
