I'm working on custom component where author will provide file name and file path in dialog. When user clicks on the file name then file will be get downloaded. This functionality is working absolutely file in author but failing in publish instance for XML,Excel and word files. I noticed one extra folder(dam:failedRenditions) for these types on publish instance. Can someone explain why theses renditions are failing? and why i'm unable to download only XML,DOC,Excel file on publish instance?
