## File hoster downloads

Not every file is on a peer-to-peer network. Many are only on one-click hosters and link sites, and eMule Qt downloads those too: paste the links, and the daemon resolves them, waits out the hoster’s timers, asks you for a captcha when there is one, and moves the finished file to your incoming folder.

The heavy lifting is done by [JDownloader](https://jdownloader.org/)‘s plugins — support for more than 3,500 hosters and 1,000 link sites, kept current by the JDownloader project. eMule Qt runs them unmodified in a small helper process next to the daemon, without JDownloader’s interface, so everything happens in the eMule Qt client, the daemon and its logs.

### Adding links

- **Add links…** in the Hoster tab: one link per line, with an optional **Package Name** that keeps the files under one entry and in one folder
- **Paste links** takes every link on the clipboard
- A link to a folder asks which of its files you want
- **Download** on a web search result adds each file with all of its mirrors as a package; the links dialog can check first which mirrors are still online

### Mirrors, accounts and resume

When a file has several links, eMule Qt picks the best one first: links you hold a premium account for (with traffic left), then any account, then links checked online, and offline links last. If a link turns out dead, wants a puzzle you skipped, or keeps you waiting more than five minutes, the next mirror takes over. **Retry** starts again from the first link.

Add your hoster logins under **Accounts**. eMule Qt checks them, shows whether each is premium and until when, and knows that one login covers all of a hoster’s domains. Passwords stay in the daemon’s configuration, obfuscated, and are never sent to the interface.

A transfer that breaks continues where it stopped when the hoster allows it. **Downloads at once** limits how many run in parallel (two by default), and never more than one per hoster and account, as most hosters require.

### Captchas

When a hoster shows an image puzzle, eMule Qt shows it to you. **Skip** moves on to the next mirror; **Skip hoster** skips every puzzle of that hoster until you retry a download there. Puzzles that need a full browser — reCAPTCHA, hCaptcha, Turnstile — cannot be solved yet; such links end as *Needs you* and the next mirror is tried. While a download is still getting ready, the Status column tells you what the plugin is doing: opening the link, logging in, solving a captcha or connecting.

### Checked twice, shared once

Hoster downloads run on eMule Qt’s ed3k node. When a file is already known there, every block from the hoster is verified against it and other ed3k peers can deliver blocks too, so a corrupt or swapped file is caught on the first bad block instead of after the download. When it is not known, the file is hashed once complete.

After a successful download eMule Qt shares the working link with other ed3k nodes, so the next person looking for the file finds a link that is known to work; it checks the link again every few days and withdraws it once it goes offline. Links other nodes share are used when your own link fails, each verified block by block.

### Java, handled for you

The plugins need Java 17 or newer. eMule Qt uses one it finds on your system, or downloads Eclipse Temurin from adoptium.net, checks it against its SHA-256 and keeps it in its own folder. Nothing is downloaded or unpacked until hoster downloads are allowed, and switching them off removes the plugins again.

> **Turn it on**

> Hoster downloads are **on by default** and need the ed3k node (**Options → ed3k → General**). **Options → ed3k → Hoster** holds “Allow downloads from file hosters”, the Java runtime, downloads at once, “Show image puzzles (captchas)”, link sharing and your hoster **Accounts**. The **Hoster** log tab shows what the helper does; “Log hoster resolver details” under **Options → Extended** adds every step.
