How to import your library from Version 1 into Version 2
When you first launch Delicious Library 2, it should migrate your version 1 data into version 2 automatically.
If it didn't, or didn't completely, here's what to do:
1. Close Delicious Library 2.
2. In your home folder, find and delete the Library > Application Support > Delicious Library 2 folder.
3. Relaunch version 2. It should import the data from Version 1 on its own.
Also, please be aware that some of your items may now reside in a different collection. For example, Audiobooks may now be under Music, and Games may be under Videogames or Software — or occasionally Toys.
To move items to different collections in version 2, select all the items you want to move, then select the button, then find the field called Item Type and choose which collection you'd like them to live in.
Warning!! If you have data in Version 2, deleting the Version 2 folder will delete it.
