What kind of media files? Music files, photos, videos, movie files etc.? When you say restore W7, are you implying that you had W10 installed on your computer and then restored to W7?
In most cases, unless you are talking about
iTunes music library files; W10 does handle music files differently as WMP (Windows Media Player) files were changed in W10 with
Groove Music (built-in to W10) or another W10 media player.
It would help if you could be more specific with your question. Also, it's Customary on this forum and most other Tech Forums to at least provide us with the Make/Model of your computer? Desktop or laptop? OEM (Dell, HP, Acer, Toshiba) computer? Self-built computer with parts you purchased and assembled yourself, or a Custom-built computer which you paid someone to build for you from specs and parts list you chose.
If you have either a Self-built or Custom-built computer; please provide
FULL hardware specs:
Make/Model of Motherboard, Make/Model CPU chip, Make/Model GPU chip/card, RAM stick Make/Model/Type; PSU Make/Model/Wattage. We can assist you better if you are willing to provide us with this information.
If you don't have specs on your computer, you may wish to download the free
SPECCY diagnostic program from
piriform.com run the program and upload the resulting output text file (.txt) back here to this thread. You may not be able to upload for a few days since this is your 1st post; so you may have to comment on a few other people's questions--if you can, and then once you have a few posts under your belt you'll be able to upload your computer specs to us.
Thanks for the additional information in advance,
Best of luck
