I'm hoping to have a discussion about software that can be used to organise collections of magic videos and recordings on a hard disk. Is this the right place in the cafe for it?

Have a look at Notion. You can create a database for your needs with access on different ends. It is free if you don't collaborate with others on the platform.
Well, you have to type in all your informations but then you can search for all kinds.

Thanks I will check it out. I have quite a lot of digital files of lectures, downloads, product instructions etc and was hoping to categorise them better for easier reference.
