How to make the file lighter?

I have a file that is already in its third revision and some things have been removed, but the file size has not decreased. I would like to know if D5 Render has this option to make the file lighter, like purge in Sketchup.

Hi @paloma.bonani

You can try “Clear Data” but please be aware of the warning prompt. You may save a backup of your data and try to do the process just in case this feature is not what you were hoping for since it will also clear the imported list.
