What is a DLC container?

A DLC container (Download Link Container) is an encrypted file that bundles and protects several download links. Instead of sharing individual links in the open, you pack them into a container – this protects the links from automated harvesting and makes sharing entire download collections easy. Zaulto brings this concept to the browser: no installation, with password protection, captcha and access rules.

What is a link container for?

Anyone who wants to share several related download links – such as a multi-part archive or a set of mirrors – faces two problems: long link lists are messy, and openly posted links are quickly harvested by bots, reported or blocked. A container solves both by managing all links bundled and encrypted.

The recipient receives only a single short reference. The contained links are released only when the container is opened in a controlled way – with Zaulto secured by the protection rules you set, such as captcha, a password and geo/IP rules.

DLC, CCF and RSDF – the formats in brief

DLC (Download Link Container) is the most common format and uses a client-server model for encryption and decryption: the actual link information is processed on the user's side, while the server only handles the key exchange. CCF and RSDF are older container formats with a similar purpose, but are rarely created today.

In practice, DLC is the most relevant format because it is supported by common download managers such as JDownloader. Zaulto hands a container's links to JDownloader via Click'n'Load; Zaulto's optional .dlc file, by contrast, is its own format with the links in readable form, not an encrypted JDownloader DLC.

How do you open a DLC container?

DLC files are binary and encrypted – you cannot simply read them in a text editor. To open one you need a download manager that understands the format. The most common is JDownloader: add the container, and the manager decrypts and displays the contained links.

With Zaulto there is no need for the cumbersome file route when sharing: you manage and protect your links directly in the browser and only pass on a single secure container reference – without any local software.

Why Zaulto instead of loose link lists?

Zaulto combines the advantages of classic containers with modern web security: your links are stored encrypted on the server and are only delivered once a visitor passes the protection rules you set. For each container you decide who may access it, when and how often – with a password, built-in captcha, geo/IP rules, time and quantity limits as well as stealth mode and automatic protection (AutoProtect).

All of this works without installation, data-minimal and without tracking – on your smartphone too.

Create a link container with Zaulto – step by step

In just a few steps you bundle your download links into a protected container:

  1. Sign in: Sign in to Zaulto. A free account is enough to create containers.
  2. Add links: Add your download links to the new container – individually or as a whole list at once.
  3. Set protection: Choose the protection options: optional password, captcha, geo/IP rules and time or quantity limits.
  4. Share the container: Save the container and share the generated secure reference. The contained links are stored encrypted on the server and only delivered after the access check.
