Regarding the choice of extension for BigTIFF:

For what it's worth, I have just learned the Adobe released new  
version of their PSD format back in 2005, called "Photoshop Large  
Document Format".  This change was very similar to that of BigTIFF in  
that a few of the pointers changed from 4 to 8 bytes.  They also  
changed the file header from "8BPS\0\1" to "8BPS\0\2" so the new file  
format could be identified (this was a version number change  
according to the specification).

Adobe uses a different extension for these files (PSB instead of PSD).
