Fast file sever through wifi network

Hi, can you recommend me a fast file sever over wifi?

I have old unused Lumia 1020 phone with big storage and I want to share all data (songs, photos, ...) to other devices connected to my network.
Actually this phone working in windows phone 10 system but if it necessary then (maybe) I downgrade it to 8/8.1 version .
Thank you for help.
