full screen not extending

full screen not extending its on full screen but on left and right sides it is black I tried to change from dosbox but I cant find right way

The game doesn't have wide screen support even with full screen. It wasn't designed around 16:10 or 16:9. That's why there's two black bars on the side.

You'd need the Daggerfall Unity mod to make it widescreen compatible.

Daggerfall doesn't have native widescreen support, but DOSBox (the emulator running Daggerfall) has.
Daggerfall Unity is not a mod, and it's not required to make the black borders disappear and play Daggerfall with widescreen resolutions:

- Open df.conf in steamapps\common\The Elder Scrolls Daggerfall\DOSBox-0.74 with Notepad or another text editor (I recommend to make a backup of the original file first).
- Scroll down to the "aspect" line and replace it by
aspect=false
This makes the black borders disappear.
- Scroll back up to the "fullresolution" line and replace it by something like
fullresolution=1920x1080
(or whatever your resolution is).
- Two lines further down, you could replace the "output" line by
output=ddraw
if you want better graphics.
Save df.conf and launch Daggerfall.

Edit: To avoid misunderstandings, I changed "aspect=false." to "aspect=false". The dot must not be copied into the config file.

I have tried that and it didnt work I dont know why so I instaled unity and it works fine and it also changed some controls too and it is lot better now thank you for your time

Have fun! Just be aware that Daggerfall Unity isn't Daggerfall. If the differences are major or minor, significant or not, and make Daggerfall better or worse is a matter of opinion.
With that said: Unless you're interested in playing the original game, these differences are probably irrelevant for you.

The method I described works 100%. I only forgot to mention that I assumed you were playing Daggerfall in fullscreen mode. If you play in windowed mode, the method won't work.
In this case you would have to change the "fullscreen" line (near the top) by
fullscreen=true
