ThreadText: # How to delete Calibre ePub bookmarks
  
  (Asked by: username_0 on 2014-12-03)
  
  Whenever an ePub file is opened with Calibre's ebook viewer, a bookmark file is created inside that ePub. This file does not store user bookmarks, it is automatically used by the program to remember the last used location inside the book.  
  More precisely this bookmark file is called `calibre_bookmarks.txt` and is located in the `META-INF` folder, inside the said ePub book main directory.
  
  I'd like to know if there is an easy way of getting rid of these bookmark files from inside Calibre, ideally from multiple ePubs at once (doing it manually for every single ebook wouldn't be very handy), effectively cleaning them and restoring their "newness".

  There's a plugin called [Modify ePub](http://www.mobileread.com/forums/showthread.php?t=154371) which could remove Calibre bookmarks. But I haven't tried it myself.

  There is another way to do this on Linux.
  
  First, open a terminal and `cd` into the folder with your ePubs.
  
  Next, type the following command: `find . -name "*.epub" -exec zip -d '{}' 'META-INF/calibre_bookmarks.txt' \;`
  
  Then, all of the calibre\_bookmarks.txt files inside all the ePubs in the current dir (recursively) will be deleted.
