Sorry but i have a old samsung galaxy q or sgh-589. And i was wondering if anyone knows how to back up FOLDER Booknarks?

I labelled 6 or more folders for different subject on the intetnet and put the bookmark shortcut into each folder according to the topic. For example
folder named Wikipedia has all subjects to do with wikipedia etc...

I had close to 40 or more bookmarks in each folder. Then one day i lost all of it.
Really pissed me off because i cant remeber all the different url adressess that oi visited.

Can anyone help???
