Using igor script to create folders in the hard-drive.

Hello fellow Igorians,

I'm using SavePICT to save snapshots of my analysis graphs as the script plows through the data.

Because it is a lot of data It would be better if I could from within the script create an arbitrary number of folders in the file system, where I would save related images.

I stuck in that I don't seem to identify the function that would allow me to create folders in my file system via Igor scripting - could anyone point me in the right direction?

Many thanks,

Ricardo
