title: How to modify a single file inside a very large zip without re-writing the entire zip?
body: <p>I have large zip files that contain huge files. There are "metadata" text files within the zip archives that need to be modified. However, it is not possible to extract the entire zip and re-compress it. I need to locate the target text file inside the zip, edit it, and possibly append the change to the zip file. The file name of the text file is always the same, so it can be hard-coded. Is this possible? Is there a better way?</p>
