Importing comics

I’m trying to import comics from my usb c drive and it’s not working as it should.

When I import I cannot select a folder that has comics in it. I have to go into the folder for example Spider-Man select all files and open to import them into a folder on my iPad. This works if there are only a few comics in the folder but does not work if for example there are 200 comics in a folder, it copies some but not all for example 68 out of 209 in said folder.

Any ideas?
