To share a file, select "Share" from its actions menu:

A window will open where you can see your Auth Token after it's generated and can share the link of your file with anybody to view it.

If you want to share it privately, just place your file in the "Encrypted" folder and then share it, you'll then need to select the Züs user(s) with whom you'll be sharing the file, by writing their user names and then clicking "Add".

You can then view all your shared files in from the "Shared" page which you can find in the left menu.

## Private Sharing You can also share your files privately with only some users, and revoke access for any of them anytime. 1. First, make sure the file is uploaded into your Encrypted Folder on the Homepage.

2. Choose a file, and select "Share" on its file operations. (the three dots).

3. Input the profile name of the user you would like to share the file. Next, click "Add."

4. Congrats! You have privately shared a file! {% hint style="info" %} Our decentralized technology (Proxy Re-Encryption) ensures the file is shared securely with absolute privacy. {% endhint %} ## Sharing an encrypted folder You can share a whole **encrypted folder** — and keep adding or updating encrypted files in it **without re-sharing**. Thanks to Züs proxy re-encryption, the share keys stay the same, so everyone you shared with automatically sees the current contents. 1. Open the **Encrypted** section from the left menu. Create an encrypted folder there (**New → Create Folder**) and put your encrypted files inside it. 2. On the folder, click the three dots and choose **Private Share**. 3. Share it privately — encrypted folders can't be turned into public links: * **Selected Users** — search by username and add specific people. * **Shared With Groups** — share with a whole **group (data room)** at once.

Private Share dialog for an encrypted folder, with Selected Users, Shared With Groups, and Shared With tabs — Sharing an encrypted folder privately — to selected users or a group

4. Afterwards you can **add new encrypted files to the folder, or update existing ones, without re-sharing** — the people (or group) you shared with keep access automatically. To remove someone, open the **Shared With** tab and revoke them. ## View shared files 1. To view shared files, navigate to "Shared" on the main tab.

2. Here you can see all files shared **to** you and **by** you. Both **standard and encrypted** shared files (and shared folders) are listed together in this one place.

## **Revoke Access** 1. Select a shared file, and click "Share".

\ 2\. Here you can track all users that have access to your file. Click in the trash can to revoke access:

3. You revoked file access! {% hint style="danger" %} Renaming or deleting a shared file will cause it to be unshared. Users cannot access shared files after they are renamed or deleted. {% endhint %} --- # Agent Instructions This documentation is published with GitBook.
