Zipeg
Zipeg is a file compression tool, which offers the convenience of
previewing an entire file before extracting it. It supports popular
archiving formats such as ZIP, RAR, 7Z, TAR, TGZ, BZIP2, ISO, CBR, CBZ
and many others.
With Zipeg you can open a compressed file, sort file-names in
alphabetical order, view its content and extract the content from it.
It also supports auto-detect file-name encoding and you can preview
images, not just various documents. Zipeg supports content extraction
from password protected archives that are encrypted, such as ZIP and
RAR files including those that contains multiple parts. There is an
Options button that allows you to select the file you would like the
application to open by default, and also where you would like the
destination file to be placed.
Zipeg is a great tool for previewing compressed files. For its
functionality, it really is quite lightweight and uses hardly any system
resources. It has a clean interface that can be navigated by users of
all levels of experience, as there is virtually zero learning curve;
simply install and use. The only downside is that Zipeg is unable to
create archives, but then again, it doesn't claim to.
Note, Zipeg requires Java to operate.
