Can we delete the content of backup folder of launcher?

This folder …\Unreal Engine\Launcher\Backup size is 98% of all Unreal Engine, can we delete is without any problem?

I have removed using the launcher all the old versions and vault items and this Backup folder still is occupying 15gb.

Hi, of course you can delete it.

That folder have sense in situation when your projects doesn’t work and you want rollback, that problems have mainly C++ projects with Third party compiled(-only) plugins.

If everything works you can delete it in peace with Launcher.

Great, thanks. I work with Blueprints projects only, everything is working fine, and I’m not even using 4.6 anymore, the biggest backup folder says 4.6.
Regards.
