2010.02.04 21:47 "Re: eta for bigtiff support?", by Chris Cox
Yes, and around that time I brought the same arguments and reasons to the
libTIFF team.
And they rejected the idea of a different extension.
PSD had problems going to a new version because too many third party
implementations were not even checking the version number (or many other
size fields) when reading the files.

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).
