OK, suppose a Mac guy really did build a PC to run his old Poser content under new Poser versions.  How about file format compatibility?  Since I've never used a PC, I don't know what the tricks are to transferring Mac content to a PC disk.  Could I say copy a folder of Poser content, .cr2 files for example, onto a USB drive, insert that drive into a PC, copy them to the PC hard disk then open them with a PC version of Poser?  No file format incompatibilities?

After viewing some videos on building a PC it looks not that hard but I am apprehensive about all the software issues a Mac guy would have to learn about.

Thx for the many useful, clarifying comments above.
