Reduce Harddisk Space of Katalon Studio by removing update data

In our company I have just a client with 100GB disk space.

After using Katalon Studio over a year and updating it, I found out, that the updates are still stored.

I found out they are stored in the following folder: [Install-DIR]\configuration\resources\update

After removing the folders of old versions (5.1-6.2) I got 3.2 GB more free space back.

Maybe this hint helps someone too?
