## What is it?

Blender keeps preferences, the startup file, add-ons, extensions and presets in one folder per version (for example 4.2, 4.3) under `~/Library/Application Support/Blender`. Old folders stay after you upgrade. They are usually small, but downloaded extensions and add-ons can make them larger.

## What happens if you delete it?

A deleted version folder is not recreated unless you run that Blender version again, which then starts with default settings. Your .blend files are stored elsewhere and are not affected.

## How to remove it properly

Keep the folder of the version you use: Blender offers to copy settings from the previous version only when a new version first launches. Quit Blender and move older version folders to the Trash.

## Before you delete it

If you still open an older Blender release for compatibility, keep its folder, or you lose its custom keymaps and add-ons.
