Problem:

Would like to change the location of Revolve.log file from default of c:\\ to a different path structure.  How is that done?

Resolution:

changing the location of the revolve.log file:

relocating the default directory to a different drive and path  

Add this to global.def:

[DEFAULTS]

DIR=X:\\                  (or whatever the drive letter and path is)

This will relocate the revolve.log file.
