file copy

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

'send' is the definition.
I know nothing about this answer so I can't tell whether this works.

'column keeping this for the record?' is the wordplay.
I cannot quite see how this works, but
'column' could be 'file' and 'file' is found in the answer.
'record?' could be 'copy' (copy is a kind of record) and 'copy' is located in the answer.
No letters remain.
This explanation may well be incorrect...

'in a' acts as a link.

Can you help me to learn more?
