Where does MIk store its data so that i can restore it on another PC please? Is there a folder i can copy over?
You can find the database file here:
C:\Users\YOUR USERNAME GOES HERE\AppData\Local\Mixed In Key\Mixed In Key\YOUR VERSION\MIKStore.sdf file.
Please note that the AppData folder is a hidden folder, so you will have to set your PC to display hidden files and folders to see it.
p.s. since you will be moving the db file to a new computer, Mixed In Key will probably not be able to find the analyzed files since it has a new location. So, you will probably need to relocate the files in your collection again.
Let me know how it goes.
