Navigating a Zipped Filesystem

Question

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 my-zip-file.7z, containing folder my-folder, with files this-file.docx and that-file.html I can use 7zip to go into my-zip-file.7z and open the 2 files, and see or change the contents, even if the original my-folder is deleted! How is this possible?

Answer 1

If you look at the file path for whatever you're editing you'll see that the document is saved to a temporary folder. When you save (or possibly close) 7-Zip then updates the zip file with the saved content.
