Hi Lital,
I'm unaware of a way to do what you are asking, unless you also come up with your own file handling code for it. Are you wanting this so that everyone has access to the files? If so you can already do that with the Folder resource, which by default the teacher manages the file structure and uploads, but students can access them for use. And if you REALLY want everyone to be able to change whats there by creating/deleting folders and uploading/accessing/deleting files, then go to the Administration > Permissions for the folder and add students to the Activity:Folder > Manage files in folder module setting.
This change will let any teacher or student in the Moodle course create folders and drag and drop files into the folders, including zipped files that contain subfolders. Just right click on a zip file and select Unzip.
The downside to this is that students can do things to the files and folders you might not want them to do, that can affect the experience of other users. If that is a problem, just use the Private files block instead which makes it so everyone is limited to and responsible for their own files.
