The following options allow you to specify the name and location of the file you're about to save:
File Name
Type a new filename to save a parameter file with a different name. PC1D automatically adds the extension you specify in the Save File As Type box, if you don't supply a different one.
Save File As Type
Choose between the latest version of PC1D, or an old file format which can be opened by older releases of PC1D. Of course, new features can’t be saved in the old format.
Drives
Select the drive in which you want to store the parameter file.
Directories
Select the directory in which you want to store the parameter file.
