What is ApplicationsStorageExtension on the Mac?
If you're running macOS Ventura on your Mac or MacBook when you click Settings > General > About > Storage, you'll notice that the ApplicationsStorageExtension appears to be related to the 'Storage' calculations available.
The process is started when the memory analysis screen is available on the screen, but it often continues to run with high CPU and memory usage even after the memory breakdown is complete. This makes the process a bit strange, as you would think it would stop running and consume resources once the calculations are complete.

Why ApplicationsStorageExtension high CPU usage occur?

2. Launch many apps at one time
Well, if you have several heavy apps in your system such as Photoshop, Adobe Premiere, and other graphic designing apps, and you have opened all of them simultaneously, it may result in high ApplicationsStorageExtension CPU usage. To fix it, you can close apps on Mac.

Whenever you turn on your Mac system, Mac startup programs load along with the OS, which leads to ApplicationsStorageExtension high CPU usage.
