I am having so much trouble with Corel2018 with crashes and file save errors, that I am worried about losing access to important work And as such, I am considering switching back to Corel 2017 before I lose access completely. I had fewer issues with Corel2017 and fewer complaints.
But obviously, every file I have updated to 2018 has been resaved in 2018 format and will now not open in 2017.
So, can I save (in 2018) my files, to be compatible with an older Corel version like Corel2017?
Use 'Save As...' command under the menu File. Once you get the Save As dialog, click on the down arrow for the Version number and select Version 19 (2017)
