[Therion] File transfer from PDA to Mac?

Anyone know of a simple way of browsing/transferring (PocketTopo) files from a PDA (I have a Dell Axim X51, running Windows Mobile V5) to a Mac (OS 10.11.1)? Transferring files to a pc, and then to a Mac is an option (but I don't have a pc, and would prefer not to go via a pc emulator on the Mac). Thanks
