I also save the Vectric Cut2D files in the same folder, with a "C2D" appended into the file name.

A typical file name might be "UpperRibs_DVCD" which tells me that this file was created with DevCadCamPro. Yes... I know that the Windows operating system will create the suffixes automatically, but sometimes these can get confusing, and I want to be able to identify everything at a glance.
