Relocating plugins

(Sorry for my English I’m French)
I've just received my force today and have issues downloading my plugins. I have to connect my hard drive to use them; they are not downloaded into the Force.
I just want to relocate the synths on my external drive (melotron, odyssey and solina) into the internal. Thanks

You can't put the synths on the internal factory drive, they must be downloaded to one of your attached drives. Generally speaking it's worth getting an SSD drive and installing to the internal SATA port, then use this for all your content.

Ok, I get it, thank you very much for your quick replies, I will definitively purchase that asap.
