Excel linked to another file when opened after created by macro

[Sepop]

Hi,

I created a macro that copies a new tab into a new file and completes this new file from the one that it comes and after it finishes it saves this file. When this is over, I check the file and it is not linked, but when I close it and open it again it is linked to the source file (the one from which the tab came from).

I am not sure why this is happening since I dont have any cells linked to that file and before closing it, it was not linked.

Any thoughts on this?

Thanks!
Sebastian
