Wanting to access a specific art file and copy it so as to use it in Word or another program. ???
A LightBurn
.lbartfile is a proprietary binary file format used to store saved artwork collections in a compact, reusable library.
Vectors you cannot load into Word. Images can be pulled onto the Lightburn grid, then saved as image files. I have no image files in my art library, so I do not know if you can copy from the design grid and paste directly into a Word document.
You can get vectors by pulling it to the grid, and then using the Preview window. You can then save the image from there.
