Re: How to get my plugins to my new computer
I would reinstall, those that use an installer, all programs and plugins. You'll have to re-register your programs and plugins I think.
Some free plugin .dll files can just be copied.
If you make proper project folders with all needed sounds they can just be copied as well. I don't know how Ableton or FL Studio handles project folders.
When it comes to samples that are not included in your project folders you might have to re-direct your DAW to them again.
I've yet to migrate to a new PC but these seem like the logical things to do.
