DLC, CCF and RSDF are encrypted link-container formats: they bundle several download links together and shield them from prying eyes. This page compares the three formats briefly and shows which one is relevant today – and how Zaulto positions them.
| Format | Meaning | Encryption | Relevant today? | Readable by JDownloader? |
|---|---|---|---|---|
| DLC | Download Link Container | Client-server key exchange | Yes – the most common format | Yes |
| CCF | Click'n'Load Container File | Own container encryption | Rarely – older | Yes |
| RSDF | RSDF container | Symmetric container encryption | Seldom – outdated | Yes |
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. DLC is supported directly by common download managers such as JDownloader, which makes it the format of choice.
CCF (Click'n'Load Container File) and RSDF are older container formats with a purpose similar to DLC: bundling several links encrypted. They are rarely created today but can still be read by JDownloader. For new containers there is practically no reason to use CCF or RSDF instead of DLC.
In practice, DLC is the right choice: widely supported, current and compatible with Click'n'Load. Zaulto exports your containers in the common DLC format and additionally offers Click'n'Load – you don't need CCF or RSDF for that. This makes you instantly compatible with download managers such as JDownloader.
In short: DLC is today's standard, CCF and RSDF are largely history. With Zaulto you create DLC containers right in the browser – encrypted, access-protected and instantly compatible with JDownloader.
