Opera: control of offline special website data ?
The allocated HD space for offline data from websites, not the Cache, is enormous!
opera://settings/content/all
"Von Websites belegter Speicherplatz insgesamt: 7,1 GB"
From web sites allocated space 7.1 GB !
WTF?!
100s websites save massive data on your computer in Opera - secretly !

Some pages i cant even remember to have visited them:
Used: 3,6 GB, 809 MB mozilla, 537 MB google and many more.

Question:
Is there no Opera option, addon or external App to see and control that??

More questions:
Is this a special cache for sites outside the normal cache?

This has nothing to do with "clear browser data"?
cache, cookies, history, hosted app data, ..
opera://settings/clearBrowserData

Nothing to do with Web worker, wervice worker, which also uses "secret" space on my computer?

It could be a big security leak, tracking?

thx

@cratte Mine uses a lot less. It depends on what you store there.

If you have open video or media tabs, the browser will store more data in your RAM (open streams) and possibly also in your local storage (stored media files or sections).
You can limit the amount of cookies and data that is stored if you set Opera to delete it when you exit at: 'opera://settings/cookies'
If you're storing website data on a drive with large file allocation sizes, smaller files will be bloated. I.e. each 0 b file become from 4 kb (normal drive setting) up to 2 MB+ (bad setting for browser drives).
You could try to clear browsing data and use the Advanced option under 'opera://settings/clearBrowserData' to do a more thorough data clear. Note that this will make websites forget you, so you might have to log in again. If Opera is unable to clear this data for some reason, you can manually clear it at: '%LocalAppData%\Opera Software\Opera Stable\Cache' (Windows).
