I don’t see the file/folder management capability in P2 Viewer that you describe. How exactly are you using p2 viewer to consolidate your p2 folders into a single, huge virtual p2 card?
I have a 40 minute clip spanning 2 p2 cards that’s in 4 files; Avid is only seeing the first even though MediaTool can “see” the filenames in the Avid MediaFiles folder.
