Very good point.
That being said, there are websites that can convert Ai files to CDR files and vice versa. (And to EPS too)
This one for exemple: https://www.zamzar.com/fr/convert/cdr-to-ai/
But uploading logos in EPS would be simpler.
nice point love it
eps files can be a problem in corel if exported from illustrator, The filters have some major issues at times so not so good for a corel user
Great idea as for me
