Video files are cached locally in the original - it's too much for my volume c:\

Hi community,

I've noticed, that all my videos are cached locally in the original. This causes me problems, because these are some mp4-files, which are partly about 5 GB in size. So my local systme-volume is no longer sufficient. It's too much size for that volume c:\

How can I prevent this behaviour? I don't want these video files not in the local cache.

Many thanks in advance.

Greetings,
Christoph
