Not only does this let you download as many files as you want together, but it also removes the limited size that some websites have. FileSonic's 400mb is no longer a problem.
It also removes any wait time, for the inpatient types.
Also removes all captchas.
1 - Open multiple tabs, as many tabs as there are links for the download you want.
2 - In each tab, open http://tigerleech.com/
3 - Enter Link 1 in tab 1, 2 in 2, etc.
4 - Click Leech on tab 1, start it, go to tab 2, start it, etc.

Please note: if you do not do it this way, the site will force you to wait 20 minutes between leeching, or 2 minutes with ads. This way, there is no waiting.

That's it. No extra downloads, plugins, extensions, connections, ISPs, anything.

PS - as of writing this only FileSonic and WUpload works at the moment. The admin is very good and fast at keeping up, so the others will be usable again soon enough.

 

Neat. Too bad my connection's not good enough to even bother with multidownloads anyway. But hey, if this bypasses the waiting period between downloads, I'm all for it.

 

does this bypass the capachas that you get with jdownloader? as a lot of stuff uses fileserve now.

 

You're not downloading from the host, you're downloading from a server that gets premium access to that host.

Also these sites are generally lame and not safe, it will know how much you're downloading and will limit you too (with the site in the OP, you're only allowed 7 connections max and jDownloader default setting is 2 connections per file (if possible))

Edit: I don't even know how you guys can trust a site where the admin can't even spell

 

Maybe they fixed it since I posted this, but as of my OP, I was having several downloads at one time. How about trying it, following the method I stated, not just assuming how to do it right?

@prowler - Costello makes typos sometimes to. Unlike how you seem to always view yourself, no one's perfect.

 

This works pretty well, thanks for sharing.

 

Thanks to you I got to download a 5 gb game in 1 hour just before filesonic went down. Good stuff like that dont last unfortunately.

 

I personally use a site called http://rapid8.com/

It certianly allows multiple files to be downloaded from one site at once, however I don't know if its all that great of speed, or if its just the host site that gave me slow DL speeds. But the ammount of sites it offers is pretty nice.

 

Tried to download something and got redirected to their index page. Needless to say it didn't work for me.
