Adding a HDD with windows in it to a new pc

Hi
I am buying a new pc with an SSD but my old HDD has all the files.
How do I add without losing my files.
Also, do I need to unistall windows 10 from it?
Thanks

just install the drive and your new system will boot to your new ssd instead of the old hdd.

then simply navigate the drive through windows explorer to get to your files. to save space, it is a good idea to copy all you want to save somewhere and then format the drive before using it as long term storage. all the windows files and such you don't needand would be just taking up space for no reason.
