Is there a way to delete a file from recent files?

[vinoff]

I opened 1 file a few days ago (by mistake) and now it is the #1 recent file when I search for a given query, even if there seems to be a better result.

I want to delete that entry. Is this possible?

Those files are stored in main.shada file which is located in ~/.local/state/nvim/shada/main.shada. You could delete the entries you want from that file and restart Neovim to take effect.
