Backup JW Library Data

The Faithful and Discreet Slave have given us a great tool with JW Library but if we need to install it on another machine for whatever reason it largely requires a re-download of all the books and media which can be tedious.

This guide will describe the process of backing up and restoring the information using Windows 10.

Step 1: JW Library Now Crashes

It's possible that you've copied over the WatchtowerBibleandTractSo.45909CDBADF3C_5rz59y55nfz3e folder to the location on the new machine. This will cause issues because Windows has special permissions on this folder and some of the other folders.

The fix is simple but time consuming so first you need to uninstall JW Library. You can do it without doing so but this will ensure that the files are completely gone.

Reboot Windows now. You'll need to do this step because even though the app is gone there are files that still seem to be open in memory even though the app hasn't loaded correctly. Rebooting Windows will clear these from memory.

Reinstall JW Library through the Windows Store and when installed run it. It might restart a couple of times but it should come to a state where it is useable. When it is at this point close JW Library yourself.

Step 2: Contact Me

If for whatever reason you're having issues please leave a comment below and I will endeavour to help you.

    Hello! This is my first time on this forum
    I would like to know, what is the file that displays the yeartext?
    In the AppData folder, I came across an yeartext html file which calls up a .js script file with the same name.
    Does that .js file contain the instructions to display the yeartext?
    Thank you.

    Question 5 months ago on Step 2

    Hi,

    Thanks for your good work.

    I would like to ask your opinion for a problem I encounter. I want to transfer my highlights and notes from jw library app on android. Unfortunatelly for some reason it crashes and I cant't do it from within the app. I don't mind if the data can be send to windows or android device. Can you help?

    Thank you.

    I tried it I believe step by step, but now when I try to start the app on Windows 10 the app shuts itself down before it opens all the way. Tried to reboot... same result

    It seems you might have copied the entire WatchtowerBibleandTractSo.45909CDBADF3C_5rz59y55nfz3e folder which will cause this issue. I'll modify the guide to add a section that tells you how to fix this but it's a little time consuming.

    I am brianjfs,

    Found your instruction on JW library backup instructive. However is there an instruction on how to back up The Watchtower Library (desktop). My operating system is windows 10. Looking forward to your response

    Hi brianjfs, I do apologise for the late reply. I've been a bit sidetracked lately.

    To answer your question kind of requires knowledge of what you're trying to backup. If it's the main application then you need to go to "C:\Program Files (x86)\Watchtower". There is a folder here called" Watchtower Library" that you can backup but restoring it or copying it to another machine requires that you first run the WTLib installer off the DVD first. This is because non-Metro apps need to install stuff to the registry otherwise they won't work. Once the application is installed then simply copy the "Watchtower Library" that you backed up into "C:\Program Files (x86)\Watchtower" on the restored machine or new machine.

    If you are trying to backup the Favourites then you go to:

    C:\Users\{your username}\AppData\Roaming\Watchtower\

    There is a folder called "Research Favourites" which you can backup and restore to the new locations. Don't worry about the "USER" folder because it's tied to your username.

    Remember that you need to turn on Hidden Files to see the AppData folder so just use this guide here right at the start.

    Hope this helps.

    Question 11 months ago on Step 2

    Very accurate tutorial, may I please ask if you know where the jwlibrary stores the images?
    We have no internet connection and would like to bring all files on flash drive to meeting. Thanks.

    If you look under LocalState/Publications then you will see a list of the downloaded publications.

    Each publication will have its own named folder for example the Meeting Workbook for February has the folder name mwb_E_201802. Inside this folder you will see the images for this publication. The same can be said for the Watchtower and Awake and the various books and tracts we have as well.

    This folder will not have the videos however as these are stored in your Music and Videos folders respectively.

    Hope this helps.
