@Moorthy – can you tell us a bit more? By mentioning "folio", I think you are referring to Adobe Digitial Publishing Suite (ADPS or short: DPS). If yes:
1. Do you want to analyze Folio files *.folio and get the linked web content files?
2. Or do you want to check an InDesign file with an overlay and check what files are linked as web content?
3. Or something else?
Where is your base problem?
Packaging the InDesign files and copy/relinking the web content files after the packaging process?
Thanks for reply.
Yes, its a ADPS. My query is "1. Do you want to analyze Folio files *.folio and get the linked web content files?".
My problem is how web content files are linked in Folio.
