Youka stores every project in a single folder on disk. Copy that folder to a new computer and tell Youka where it lives.
Steps to transfer
Find the library folder
On the old computer, open Settings and copy the path shown next to
Library Folder.
Copy the folder
Copy the entire library folder to an external drive or network share.
Install Youka on the new computer
Download and install Youka on the new machine.
Replace the default library folder
On the new computer, replace the default library folder with the folder you
copied over.
Reindex the library
In Settings, click Reindex Library and wait for the loading
indicator to disappear.
Reindex rebuilds Youka’s internal cache. It doesn’t touch your project files,
so the process is safe to repeat if anything goes wrong.
Your projects should now appear in the Library tab exactly as they did on the old machine.
