Uh ... right click on the file and select "Rename" after first jotting down the original file name that the 8801 will recognize.
Give it a name that describes something unique about the EQ ... eg. the date and some other tidbit to differentiate it from the other EQ file names. You would then have to rename it back to the original file name when reloading it back to the 8801.
I understand what you said earlier about renaming I've never had any pre/pro coupled to a PC, I'm assuming this is what you do? Excuse my ignorance, this part is new to me.
