Compact Xojo Project File

Is it possible to compact Xojo Project File?

I had deleted quite a number of items in my project file but it seems that the project file size does not reduce at all after saving.

code is not the problem.

If you need small project to send to friends, you can remove big icons.
Icons can be easily mega bytes big.

I would put the source in git. then first pull for anyone would be large. But when they pull the latest copy it would only be the diffs. So unless you are changing the icons or other images, it should be a very small change set.
