Saving files in two places at once automatically?

Hi guys,

Hope you can help. I have files on my usb stick so I can use them anywhere, but the master copies are on my hard drive. I would like these files, when I save them on my hard drive, to be automatically saved on my usb stick (assuming my usb stick is in my pc at the time!). Obviously, this could only work one way round, unless there is a way to update the version which was updated longer ago with the more recent one.

Any ideas?

Thanks

 

Ok

Thanks Pete, I'll give it a go when I get home.

 

Worked a treat, thanks
