Q:

How to remove Mesh Data of a Blend File?

Hi recently I was working with big files in a Blend file now I decided to separate the Objects so well I was able to do that but now I just have one object. But I have a lot of mesh Data.

As you can see I only have one Object in the scene called "Banquita" but It seems that I have A lot of "Meshes Data" inside the Blend file that increases a lot the size.
I already check DataBlocks but there's not option for this, delete the Mesh Data.

A:

Well it was more easy than I thought. Just go to the Outliner, change to the Blender File. There you can see all the data of the actual .blend file 

Select all the unwanted meshes and right click Delete . 
That's all.

A:

When you delete an object, not all information about it will be deleted. Its mesh data will remain in the file.
Of course, you can try to delete this data one by one, or try to re-open the file several times, but there is a way more simple:
So if you want to delete the unused mesh data, open Outliner in Orphan data mode and click on Purge All - it will delete all mesh data that are not used in the scene.
