Frequently asked questions (FAQ)

What is a link container?

A link container bundles several download links under a single, short address. The links are stored encrypted and only become visible after the visitor passes the access check – ideal for sharing collections securely and neatly.

How does Zaulto protect my links?

Every container can be secured with a password, a captcha and geo/IP rules. Links are stored encrypted and are never served in plain text before a visitor passes the access protection.

Which captcha types are available?

Three: a simple arithmetic challenge, an invisible proof-of-work (compute-based, no clicks) and a custom question with a stored answer. The proof-of-work offers the strongest protection against automated bots.

Does Zaulto support DLC and Click'n'Load?

Yes. Zaulto generates DLC container files and Click'n'Load links that JDownloader processes directly – a single click adds all links to the download manager at once. The handover only happens after the access check has been passed.

Does Zaulto work with Internet Download Manager (IDM)?

Zaulto generates DLC files and Click'n'Load links for download managers such as JDownloader, which handle this container format directly. Internet Download Manager (IDM) does not support Click'n'Load or DLC. However, after unlocking you can copy the links contained in the container manually and paste them into IDM.

What are DLC, CCF and RSDF containers?

DLC, CCF and RSDF are encrypted link container formats that bundle several download links together and hide them from prying eyes. JDownloader can read all three formats. Zaulto exports your containers in the widely used DLC format and additionally offers Click'n'Load.

Does Zaulto support mirror links?

Yes. You can store several mirror sources for a file. Zaulto checks the links regularly and automatically switches to a working mirror if one goes down (failover), so downloads stay reliable.

Can I share large, multi-part downloads (e.g. RAR archives)?

Yes. Multi-part collections – such as RAR archives split into several parts – can be bundled as a link list in a single container. After unlocking, visitors get all parts at once, ideal for JDownloader.

Does Zaulto check whether the links are still online?

Yes. Zaulto checks the status of the stored links automatically and marks whether a file is online or offline. Combined with mirror links, it switches to a working source if one fails.

How do I share password-protected download links securely?

Create a container, add your download links and secure it with a password, captcha or geo/IP rules. You then share only the short container address (optionally as a QR code) – the actual links stay encrypted until a visitor passes the access protection.

Does Zaulto cost anything?

Creating and sharing containers is free. You only need a free account to create a container.

Do I need to create an account?

Yes. You need a free account to create a container. With an account you can also manage your containers later, view statistics and organize them in folders.

How does password protection work?

You can set a password for a container. Visitors must enter it before the links become visible. The password is not stored in plain text, and the links stay encrypted until the correct entry.

What do geo and IP rules do?

With geo and IP rules you can restrict access to certain countries or block individual IP ranges. Requests that don't match are denied access to the links.

What is stealth mode?

In stealth mode the actual container page is hidden behind an inconspicuous intermediate page. The real content is only revealed after the access check is passed – useful against automated preview and crawler bots.

What does AutoProtect do?

AutoProtect automatically masks embedded containers and places an intermediate page in front of them so links can't be read directly by bots. The settings can be adjusted per account.

Can I limit a container by time or number of accesses?

Yes. You can set an expiry date and limit the number of permitted accesses. Once expired or the limit is reached, the container is no longer accessible.

Can I organize containers in folders?

Yes. With an account you can group several containers into folders and share a folder via a single link. This keeps larger collections tidy.

What statistics can I see?

The dashboard shows data-minimal access statistics: number of views, rough geographic distribution and timelines. No personal profiles are built and no advertising trackers are set.

How do I delete a container?

Containers are always tied to an account. In your dashboard you can delete any of your own containers any time with a single click – the encrypted data is then removed.

How secure is the built-in captcha?

The captcha challenges are HMAC-signed, single-use and verified server-side in constant time. After unlocking, the visitor receives a short-lived access token, so the download endpoints cannot be bypassed directly.

Does Zaulto work on smartphones?

Yes. Creating, sharing, unlocking and the dashboard are fully optimized for mobile devices. Shared links can also be displayed as a QR code.

Who is liable for the linked content?

Zaulto is a neutral technical service and does not host target content. The creator of a container is solely responsible for the linked content. Details are in the disclaimer.

How do I report unlawful content?

You can report specific legal infringements via the contact form. Once we become aware, we remove affected containers without undue delay. Please provide the container address and a short justification.
