[Opensim-users] Load IAR - does it duplicate underlying assets?

[Ai Austin]

I wonder if anyone can help me check on how something works with load iar?

I have an IAR with a thousand or more items in it... mostly mesh and 
want to make sure I don't upload two copies to my grid.

a) I uploaded the IAR once.

b) I have an updated version with some tidy up done, some items 
renamed (but will have same content and UUIDs) and some items added, 
but 90% is probably identical to the original.

Now, do I have to be careful with the second upload and only try to 
upload the changed and new parts.. or can I just load the IAR again 
and it will not add a second copy of the contents and meshes (or make 
new UUIDs for the second copies)?  Just adding new INVENTORY items 
but keeping the originally uploaded contents.
