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).
