Hi. Your bookmarks, unless backup up are on the C: drive of a Windows system all of which is generally overwritten. In older days when the drive was a magnetic disk it was possible to search for deleted files as a deleted file only had it's first character changed so if that section/cluster of bits wasn't overwritten it was possible to collect 'deleted' files. It wasn't generally possible once a whole re-write was done. With static chip memory that is out of the question as far as I know Either way it seems you have lost them. In future, you may like to do what I do and that is copy the Profile folder often to a separate SD card etc. You can of course save other user personal data by copying the whole C:/users folder. Sad, I know the disappointment of not anticipating this
