Need Advice On Audit Log File Access

[Suhaimi Jamalludin]

Hi All,

I have a File Server and all the clients are using WinSCP3 to copy their 
data to my File Server.
Is there any audit log generated for me to check if somebody accidently 
deleted any files in the File Server.
I'm looking at simililar method like Samba-audit log.

By the way I'm using FreeBSD5.2.1

Can some body advice...pleaseee
Really appreciate your help.
