How to import existing Meta Data Alt-Text from JPG images

I just bought your WP Media Folder Extension (and all other plugins as a bundle). But I am a bit disappointed now or I understand something wrong. My basic need was to import perfect prepared images with correct titles AND THE ALT-TEXT, that wordpress copies this ALT-Text for SEO etc. to the imported image. This is not possible with WP Media Folder? Can I just create the ALT text from the title text? But I don't want the Alt text of the image to be the same as the title text and beside of this the Alt-Texts are in the JPG meta data already done.

Thank you for your answer and I hope that this is possible with WP Media Folder. If not, I am happy if you can tell me another plugin doing this. I had problems to find something, even if my question looks very simple and basic: How to import images with all metadata?

Thank you for your answer & your great plugin-work.
