Open the OEBPS folder in a code editor.A good tool to unzip and zip epub files is eCanCrusher, which works on both Windows and Mac platformsĭownload eCanCrusher, and drop the epub file on the eCanCrusher icon. after exporting your final epub file, you must unzip it.To remove all those empty PNG files, and remove any duplicate image files, perform the following steps: But it is worth it, because of a much leaner and quicker to load epub file. Unfortunately this requires some manual adjustments to the final exported epub. So, I would love to know how to 'change the links to point to just the one blank PNG.' Unless that's something difficult that a software person needs to do. I've ended up making some changes to eliminate the need for all 120 frames, but I still need some. When I saw I still had many blank png's that were fairly large, I realized it was the frame around my scrolling text frame. To me that was much easier and didn't seem to cause any problems.

I ended up changing all of the buttons in Indesign to a text frame with a space in it. I figured out every time you create a blank text or graphic frame (buttons, frames for mp3 tracks, etc), InDesign exports those as these blank png's. I had over 650 blank png's, it was difficult to know what was what. Which is the best software to use to edit it and get it back into InDesign? I vaguely recall seeing a class covering that. How do I change the links in the exported epub? I know very little code.
