File Cleaner App Concept

A concept design for an app that helps people free up space by cleaning junk files and making other optimizations.

I wanted to do a design for a file cleaning app, as this is a common utility built-into the mobile operating system or downloaded by users. I based the functionality off of Google's Files app.

The meter like bar on the left acts as a kind of useful UI decoration, as it indicates the composition of the user's storage. It can be animated to focus on the areas that the user is looking into. For example, when cleaning up junk, the junk section of the bar can expand and split into its components.
