I've Searched many websites and blogs regarding this issue and none are successful so far so i thought i could post my question in the forums.I've tried installing repositories and stuff many things i saw on the internet and they all ended up nowhere please help me with this.How can I get Dark Mode on Files application on elementary OS ?!
actually, at least in my case, selecting "Prefer dark variant" under the "Appearence" tab of Elementary-tweaks works globally for every application
You just need to install elementary tweaks as explained here - see here for installation instructions
At the moment, Files does not have a "prefer-dark-style" setting unlike Code and Terminal.
You can run it in dark mode by launching from the command line with
GTK_THEME=elementary:dark io.elementary.files but this will not work when launching from the dock or Applications menu.
Unfortunately, linking the above command to a custom keyboard shortcut using Settings/Keyboard/Shortcuts/Custom does not work either for some reason.
Note that Files is not currently dark-theme aware so some aspects of the appearance may not be ideal. `
