Open a 1bk file with 010 Editor on Microsoft Windows. The file is intended to be handled through 010 Editor's bookmark functionality; opening it as a text document may not display useful information.
A 1bk file is bookmark data and normally has no useful conversion to another file format. Keep it in its original form and use 010 Editor to manage the bookmarks.
