How to upgrade to AnkiDroid 2.0
Introduction
With the release of AnkiDroid 2.0, you need to upgrade your decks to the new (significantly improved) Anki 2 format. Besides upgrading your decks, you also need to upgrade to version 2.0 or later of Anki on your desktop if you use it. Anki2 brings a number of fundamental changes to the learning style which also affect AnkiDroid. Please take some time to read about them here.
Upgrading Decks
This guide is for Windows users; please allow 15-60 min to do this depending on your level of familiarity with Anki/AnkiDroid/PC.
If you are still having trouble after following this guide, post in the forum for personal assistance.
Please ensure that you have the latest version of AnkiDroid installed!
Part A: Backup old AnkiDroid files to your PC

Connect your device to the PC with USB cable
Open windows explorer and click on your Android device
You should see a folder called &quot;AnkiDroid&quot; listed in your device
Copy this &quot;AnkiDroid&quot; folder to your Desktop
You should see all of your decks as DECKNAME.anki files. If not, go to the backup folder and copy and paste them into the AnkiDroid folder.

Part B: Upgrade old decks with Anki desktop software

Install the latest Anki desktop software from http://ankisrs.net
Open the Anki desktop software that you just installed
In this Anki desktop software go to file-&gt;import
Now navigate to to Desktop/AnkiDroid -&gt; Change (&quot;Files of type&quot; &gt; &quot;Anki 1.2 Deck&quot;) -&gt; Choose the first .anki deck
Do the same thing for each .anki deck in the AnkiDroid folder
Check that all of your decks are now listed in the main Anki software

Part C: Copy the upgraded decks back to your device

In Anki Desktop software go File-&gt;Export and click &quot;Export&quot; button
You should see a message saying a file called &quot;collection.apgk&quot; has been saved on your desktop
Go to your desktop and copy the &quot;collection.apgk&quot; file
Now open your mobile device again with windows explorer
Navigate to the AnkiDroid folder
Right click and paste the &quot;collection.apgk&quot; file
Now open AnkiDroid, open the menu and choose &quot;Import cards&quot; then click OK
Now you should see all your decks there ready to start reviewing.

Part D: Move any media on your device to the &quot;collection.media&quot; folder
This is not necessary if you don't use media

In windows explorer open the AnkiDroid folder on your Android device again
Confirm that there is a folder called &quot;collection.media&quot; and some other folders that look like &quot;deckname.media&quot;
Open the first &quot;deckname.media&quot; folder
Select all files (press Ctrl+A on the keyboard)
Right click and Copy
Now go back and open the &quot;collection.media&quot; folder
Right click and paste
Wait for all the media files to finished moving
Repeat steps 4 to 8 for each of the other &quot;deckname.media&quot; folders
Confirm that all your media files are now in the &quot;collection.media&quot; folder
Optional: you can now delete the &quot;deckname.media&quot; folders if you like since these are not used in AnkiDroid2

Note: This method can't handle different files with identical names.
