How to save bookmarks to the file

This question was expired because it remained in the 'Open' state without activity for the last 15 days.

Hello Laureano,

I am sorry for not answering on time. As we are trying to avoid collecting history data by default, bookmarks, tabs and per-file settings are ephemeral and are a lost when the application exits. But you can enable the "Restore bookmarks" etc. settings via the settings dialog to enable these entities to be stored persistently.

Best regards,
Adam

Thank, you, Adam.

Sorry, it seems i was not clear enough in my question.

I have those options enabled. But if you rename or move the file the
bookmarks (and other settings) are lost as the file is no longer "the same".

that's why I asked if there may be a way to store that data "to the
file". But may be the question has no sense because when you say
"bookmark" you mean something external to the file by its own definition.

The thing is that I sometimes move my files from one folder to another,
or change their names, and then I lose bookmarks. so I was thinking if I
could do something to preserve bookmarks

Hello again,

I think I understand what you mean and have to admit that this is currently not implemented, neither by modifying the PDF documents in place as the Poppler library's Qt frontend does not have such functionality yet to e.g. modify the outline of a document, nor by creating a sidecar file that can be moved together with the PDF document.

Creating a sidecar file containing the bookmarks should be relatively straight forward to implement but would still have the usability downside of loosing bookmarks when the sidecar is not renamed/moved together with the file it refers to. One could try to avoid this using extend file system attributes but that will probably fail to work when e.g. using a flash drive formatted with FAT.

Another option that should be straight forward would be to create a file attachment annotation in the PDF that contains qpdfview's bookmark data but that would mean injecting that annotation somewhere and it being visible in the file, so it seems like that would be a manual procedure and could hence also be forgotten.

Best regards,
Adam
