# How To Find Which Files Get Removed by Proguard

[SOURCE](https://stackoverflow.com/a/45479785)

Use [`-printusage`](https://www.guardsquare.com/en/proguard/manual/usage#printusage) command. For example, add this into `proguard-rules.pro`:

```
-printusage com.jiohealth.patient.** { *; }
```

This will print all the unused classes, fields, and methods into `build/outputs/mapping/release/usage.txt` by default.
