Photoshop Swatches - .aco vs. .ase

Hello together,

for some versions Photoshop can create this "exchange swatches" (.ase) for other applications like Illustrator or InDesign. I wonder for what reason it would be an advantage to use the older swatches (.aco) anyymore?

For compatibility reasons towards older Photoshop versions?

Thanks for answers
Philip

The Photoshop native swatch files (.ACO) support more color modes.

..ASE files are a common denominator format.

Hello Philip,

Hello together,
