Rename HD Video Camera Files

I have always been interested in electronics and computers. I built my own C/PM micro system as a teenager and progressed from there to the System80, C64 and finally the PC. I've been a programmer and analyst for most of my working life in private and government employment, using languages based on BASIC and C. Most of my career was spent as a Senior Systems Analyst using PICK, Universe, D3 and VB6. I am now working in C#, .NET4 and SQL Server 2008/2012, but still keeping in touch with D3 (PICK).
Although I spend most of my time in a Windows (7 & 2008) environment, I also have a bit of a Unix background and dabble in a bit of LINUX here and there.
I'm currently the Manager IT at SA Police Super where I look after all their IT needs. I'll probably be here until I retire. So much to do...
