Salut, first, is the file not shared over 2GB? *Wires does not support sharing files bigger than 2GB at the moment http://groups.yahoo.com/group/the_gdf/message/21048

You might want to add in Options->Shares the extension that is not recognized by the *Wires to be shared.

Sorry, but I don't understand clearly that question:
"So my question is do the R1 through the Rxx files need to be changed to a different file tipe before packing in order for LimeWire/FrostWire to be able to recognize and share."

Anyway, I hope my post helped a bit
Ciao
