title: Navigating a Zipped Filesystem
body: <p>I have found that, with some file zippers like 7-Zip, it is possible to use files inside the created archives. For example, if I create a file <code>my-zip-file.7z</code>, containing folder <code>my-folder</code>, with files <code>this-file.docx</code> and <code>that-file.html</code> I can use 7zip to go into <code>my-zip-file.7z</code> and open the 2 files, and see or change the contents, even if the original <code>my-folder</code> is deleted! How is this possible?</p>
