Sets that are all being loaded into the same collection can be combined. Multiple My Library files can be combined by copying everything from the first <record> tag to the last </record> tag, and pasting it into another My Library file after the <records> tag.

If there’s an error in an EXML document, you can open it in Microsoft Edge and it will identify the element with the error. You can then open the xml in Notepad and find that element.
