### 2/5 — Hard drives sizes are still in GB

*2020-07-12, version 1.6.2*

The update did not take care of it. 2 years later and we still don’t have the option to set to TB. Other than that it s ok app. Dated though.

**Developer response:** In the upcoming version released next few days, the calculation will automatically convert from GB to TB.
