I am new to using AC. Is it possible to modify a project that was developped in Articulate storyline by importing it to AC? if yes, how and which file do I import?
Unfortunately this is not possible. Both programms have a completetly different file format and do not support each other.
Unless you can publish the SL file to a passive video (MP4), which can be imported in Captivate.
Structure and formatting is completely different. You cannot put a BMW engine in a Porsche car neither.
