Fork or import project increase size

I often duplicate my projects because most of them are very similar, with only minor adjustments.
but when I try to duplicate them by forking or importing,the size of the project increases:

Can anyone give me some advice?

I don’t think it would be possible to find the reason, without you giving us what changes you’ve made. A minor change for you, might be a major one for other.

In fact the picture above is just a test,I changed nothing.
I wonder if others have the same problem? anyway thanks for your reply :smile:

Something for @will @vaios to check out.

Yes. This has been with us for quite a long time and is very annoying.

I really hope they can fix it,since the backup of the projects can be painful,especially when they are large.
