Overwatch keeps "reclaiming disk space"

Hello! I have been playing overwatch for years now, but a month ago I decided to move the game to my hard disk.

Every thing is fine, except, every ~hours i’d say, overwatch does a little update saying « reclaiming disk space » to be honest it’s very annoying as I have to close my game every time because it makes me lag a bit.

Does anyone have a solution for this? I don’t mind Overwatch updating, but every hours is a bit too much and annoying. I saw A LOT of people having the excact same issue but with World Of Warcraft (here is the forum link : Battle.net app keeps initializing and reclaiming disc space for WoW - Technical Support - World of Warcraft Forums)

I really hope there is a way to fix this because it’s starting to annoy me a bit…

Thank you !
