7-Zip 9.20 (2010-11-18) for Windows

A decent file archiver, compresses and extracts a variety of archive and file types!

How paths are stored in the archive.

It is possible to add entire group of files, folders and even source wildcards. Paquet Builder supports storing relative paths: just click on "Modify file compression".

You can set the file compression level (how hard your files are compressed): several pre-defined levels from Fast to Ultra are available. Click on "Modify file compression".

It is possible to change the compression method at any time: if you prefer to compress your files into a Zip or a Cab archive, just select the new method by clicking on "Modify file compression" again.

You can therefore compare the compression ratios between Zip, Cab and 7z.

You can save a project file (.pbp extension) and rebuild your archive later and at any time. It is even possible to automatically compile it again directly from Windows Explorer using the context menu: just click on your .pbp file and select "Compile" in the menu.
