CSV import media import via URL. Removing URL element without losing media

Dear community,

I am in the process of batch importing 2700+ items, each of them with a pdf media component.

I have uploaded these PDFs to a folder on my server, and provided CSV import with the URLs so omeka downloads the files and adds them to the “file” folder within the install.

All is going well, but my questions is regarding the next step.

Once the files are inside my omeka s install, I will no longer want these PDFs occupying additional space on my server, neither I want the element URL to be visible on my items, if possible.

How can I do that with the CSV import batch “delete” option, without losing the actual files that are now assigned to each item?

I hope my explanation makes sense and that this helps others trying something similar.

Thanks a million in advance,
