I have problems opening Quark 4 files in Quark 5 in Mac. because Quark 5 doesn't regconize my Quark 4 files. My instructor told me I should have put the qxd extension when I saved my file in Quark 4. Unfortunately it was too late when he told me that and I can't allocate a Mac with Quark 4 in it. Is there anyway I can recover my files? Thanks in advance!
