How to backup and clear the storage completely?

Hi

I'm still new with editing as well as DR. I'm using the free version.

I have edited few photo films and few clips for some local songs as a hobbyist.

But I see the CacheClip folder became 134GB. The amount of projects I did are around 8 to 10 project. each from 2 minutes to 7 minutes maximum. In these folders, the sub folders are named scrambled and don't know how to locate a project related files and delete them or backup them.

I currently tried to use "Export Project Archive" by right clicking on a project on the launch screen.

My questions are:

1. If I take backup of each projects in this way and delete everything inside the cacheclip folder, gallery and proxy media, then when I import the archives while need to retouch the edit, will everything load fine?

2. Isn't there any way that each project related files (Proxy, cacheclip and gallery store in the project name folder? That way I could backup whole folder and restore it in future.

What do you suggest?

Thanks & Regards
Anil

What I do to delete specific projects caches is highlight all the media on the timeline, then go to the top menu & choose delete selected caches.
That’s the only way to delete caches per project that I know of.
