It doesn't work on the most particles I tried and it always gives the same error message, it seems that it won't do it because of the game folder name which contains spaces in it

Message from error window:
From: particles/dark_smoke_test.vpcf
To: particles/instanced/lanaya test/shot10/dark_smoke_test_instance1.vpcf
