Documents and data

Hi,

Documents and Data of Safari on my iPad are 195 GB and after trying every advice on the internet I am still unable to delete them. I'm almost out of storage on my 512 GB so it's becoming a really big problem as I use it for work.

Where the problem probably rised: I use VLC for Apple TV and I'm sending movies from iPad to Apple TV's VLC via Safari... I didn't realize that until lately.

Any solution of how to delete it?

Thank you
