How to get media that is uploaded through FTP into the Media Library?

I have a website, build with Enfold, with a lot (A LOT) of images. (+1200)

I had to mover the site to another server. Because of the fact that there are so much media files a normal WP import/export does not work. The systeem keeps crashing. So I had to copy all those files through FTP. That went well, it all works now BUT … those images are not in the Media Library … And that’s a problem.

I found some solutions on the internet. For example the “Add From Server” plugin. That plugin does the job … partly. Because of the fact that Enfold creates several version of a images it becomes a bit of a mess.

Also I found out (the hard way) that when I try to register the images to the media library the folder structure (year > month) gets lost … And that terrible because in the site all links to media are broken then …

SO … I hope there is someone here who can help me.

How can I import media files that are already on the server – in the correct folders – without the thumbnail-versions created by Enfold AND how can I keep the folder-structure …

Thanks for the reply …
