How to transfer images to a new site?

Question

1C-Bitrix

There is an old site with an infoblock in the elements of which, in the detailed description, there are links to pictures to be displayed on the site in a detailed view.
For example, this way

sites/default/files/images/divan-v-interere_gostinoy.jpg

if you open the images folder, then there are a lot of pictures without folders of the entire site.
How can I pull out the necessary pictures for a detailed description?
