My better worker filed beautifully? (9)

I believe the answer is:

manicured

I'm a little stuck... Click here to teach me more about this clue!

'filed beautifully?' is the definition.
(nails)

'my better worker' is the wordplay.
I cannot quite understand how this works, but
'better' could be 'cured' (after being sick) and 'cured' is present in the answer.
'worker' could be 'man' (man is a kind of worker) and 'man' is located in the answer.
A single letter 'i' remains which might be clued in a way I don't understand.
This explanation may well be incorrect...

Can you help me to learn more?

(Other definitions for manicured that I've seen before include "Digitally processed" , "well-groomed" , "digitally enhanced?" , "given quick treatment?" .)
