Auto -Bank Reconciliation in AX

Hi All

Im interested to see how the bank reconciliation process works in AX (2009)

1) what kind of  file formats are supported by AX (importing the bank statement)?

2) how does it match transactions to the entries from the bank statement?

3) how does it present unmatched items?

4) does it really work and whether or not its worth pursuing?

If someone can answer the above I would be most grateful.

Thanks
