Local cache huge size with other programs executable files!!!
When I checked which were the greatest folders in my hard drive, I notice that f.lux was one of the biggest! The folder $appdata$\Local\Packages\F.luxSoftwareLLC.f.lux_sw1dyjdkns7gt\LocalCache\Local is over 2.5G and it contains several exe files from other programs that I have installed like Postman, Spotify, Slack, etc.
Why is f.lux storing those exe files and how can I prevent this?!?!?
This is the Microsoft Store sandbox, but it seems like Postman (which we don't make) is actually writing to our sandbox?
Perhaps this app is doing some process-level hooking that makes it run in the sandbox with f.lux. You should probably ask them about that, since it's pretty unusual.
Also, f.lux should use <1MB in this folder, not gigabytes. I think if you look you'll find that our files are really tiny.
I think the best way to fix this is to uninstall and reinstall f.lux, but please leave the screenshot up for a while.
FYI, the applications that are in this folder, most of them are not applications installed through Microsoft store, they are regular applications. Uninstalling the application did removed all those files.
