Windows 10 Raid 1

Hey, Im getting a 28 GB update. I closed the launcher, copy-pasted the folder and verified but Im still getting a 28 GB - 9 hs update.
Did I do something wrong? Any of these folders should be flagged as "read only"?

ALSO: I checked the supporter packs and the Deimos Swarm Pack for example is 12 USD on Epic games but it like 49 USD on the warframe.com store. Whats up with that?
