my wife has been using InDesign (and Photoshop) CS2 version on her MacBook G4 (PPC). The Mac died a few weeks ago! The files are on TimeMachine backup. Can these files be read and further used with CC2015 on a new MacBook? Thanks for good advice. Regards, Gottfried
Yes, these files are compatible with CC2015.
I would suggest though that the first thing you do on opening any of these files is save as IDML, then resave that to .indd with a new name (Don't overwrite the original) for editing. Less chance of a future surprise that way. See Remove minor corruption by exporting
