A new PC and a Windows reinstall work the same way: your settings follow your account and come back when you sign in with it. For sound files you imported yourself, export a local sound pack beforehand and import it afterwards.
Settings follow your account
Hotkeys, favorites, categories and other settings are saved to your account automatically, and come back when you sign in with the same account on the new PC.
Sound files you imported yourself
To make sure your own music also plays on the new PC, export a local sound pack on the old PC first (it packs the sound files in) and import it on the new one:
- On the old PC: Backup/Share → Export backup / sound pack, tick the categories you need, and choose a local sound pack.
- Copy the sound pack file to the new PC.
- On the new PC: after signing in, Backup/Share → Import backup / sound pack and choose the file.
