Why does UWP Package size getting so big?

Hi,
Recently, I am developing a simple Painting game. And the entry were using Vuforia’s AR camera to scan a model, if we track the target then it would change scenes. IT didint use any complicate asset or other plug-in. But my uwp game size were so big after build. Much higher than my expected… under 1G…
Below is the process that happen through i build

  1. My UWP folder is only 322MB after unityeditor
  2. But it turns to 1.95GB while i running on Local Machine platform x86
  3. And if i would like to package it. It become to 2.71GB!!!

How can i reduce the package size??

Hi, did you exclude the .pbd files in the package build window? This should save some space.
The build folder is getting big (over 2gb) but the final upload package is with all three architectures in it about 300mb in my project.
