Moving files from a iPad/ iPhone to a PC

[satans worm]

First up, i am total luddite, and i have zero patience with PC's

Now that's out of the way, if anyone could do a step by step process on how i can move Tiff files from 'files' on a iPad (or iPhone as they are on both) onto a PC with zero loss of quality please can you help!

To put some back ground on my request...

Basically I still take film photographs (told you, i really am a total luddite) which are developed and scanned by a local shop.
The shop keeps the scans out there for a week before deleting, for the week it was out there i was actually in Manhattan and away from my PC (i live in New York)
As such i used my iPad and iPhone to download the pictures and saved them to 'files' on both devices
But now i need them on my PC so i can do a bit of dodge and burn on them but cant work out how to transfer them

I did google it and following instructions down loaded iTunes to the PC, which they claim you can move files across on, but the apps you can use did not include 'files'

Hoping a PH'er can assist please!!

Thanks for the replies, in answer to a few questions

I can’t email them( my first try) they are too large even singularly

My free I cloud storage is full:-)

The file app sounds like it might work, I’ll give it a go!
I assume I but this and it appears as an app on iTunes so I can trf like that?

Thanks
