re7zip

re7zip is a simple-to-use and handy command-line tool that can extract files from archives hosted on websites without actually downloading the packages. It supports a wide range of archive types, can extract any type of file, as well as list all archive contents.

Besides Java Runtime Environment (JRE), the download package does not require installation, so you can call re7zip's process from a Command Prompt window with "java -jar re7zip.jar". This displays all options supported by the program.

When it comes to the archives, the application can detect and open zip, tar, split, rar, lzma, iso, hfs, gzip, cpio, bzip2, 7z, z, arj, cab, lzh, chm, nsis, deb, rpm, udf, wim, and xar.

It's necessary to specify the URL to the archive (/a=...), indicate the archive's format (/t=...), list the archive contents (/l, without additional arguments), set the name and format of the file you want to extract from the archive (/e=...), as well as tell re7zip where you want to save the extracted information and what you want to call the file (/o=...).

In case of content listing, you can omit /o if you don't want to save information to file but view it in the console instead (file name and format, normal and compressed size). Several examples are listed in the Command Prompt window to give you an idea of how re7zip works. It's fast and pretty intuitive once you get the hang of the command-line parameters.

Unfortunately, re7zip hasn't received updates for a pretty long time but we're hoping that the developer decides to get this project back on track. It's very practical for users who wish to inspect the contents of an archive hosted on any website and who want to extract files without downloading the entire package.
