You should be able to. It can be handled like any other file.
Somewhat related to that question:
I discovered last night that what I thought was the exported epub file (from InDesign 5.5 on an iMac operating Mavericks) actually seems to be just a link to the actual exported files which are several layers deep within the bowels of the Mac file structure. That little file which was saved where I told InDesign to save the epub file is only about 24 KB.
I also found that changing the suffix (.epub) to .zip – as I have read in several places – does not then give me a file from which I can extract all the necessary components of an epub file.
Am I doing something wrong? If not, what files have to be gathered and how should they be assembled in order to send an epub to someone?
When you export to EPUB from InDesign, you're prompted for the name of the exported file and the Save location. You should see the ".epub" file extension in the Export dialog box. Are you not seeing that? ID CS5.5 exports epubs just fine like that.
Yes to all of that.
I've sent the file to someone to see if they can actually open the epub. If it opens, it will prove me wrong – which I hope is the case. I'll post the results when I have them.
Whew! Fortunately I was wrong. I sent the file to a friend and he got the pages when he opened it. So problems solved. I apologize for wasting your time.
