Hi TCRay, <br><br>
Go into OpenLP and click on Settings > Configure OpenLP.
Go to the Advanced section, and at the bottom of the dialogue box you should see a section called 'Data Location.' That will tell you where your files are stored.
Now, in Windows Explorer go to the path you found in OpenLP - you can copy and paste the 'Current Path' text if you need to. That's where your songs are stored; I would simply copy the whole 'Data' folder as it also has all your themes and so on in there.
On the new computer, follow the same steps to find where your data folder is. Close OpenLP, then paste the old data folder from the old PC in it's place (i.e replace the 'new' data folder with the 'old' data folder).
Restart OpenLP and everything should be there.
