Can somebody please advise the best way to open a quark file as this is not being recognised
Only ancient QuarkXpress 3.3 and 4.0 files are opened with InDesign.
You'll need a third party product like this one for more recent QuarkXPress versions:
Q2ID (Quark to InDesign) | Markzware
I use that for indesign cc 2015 and it is great.
Thank you very much, I will let the client know
