If I recall correctly, the 3.1 file picker isn't resizable. And it's very small. The small size wasn't such a problem when the filesystem enforced 8.3 file name lengths, but these days it's reasonable to expect names for individual files or folders to be much longer than that. We have a bug in our backlog right now because we tack on an extra bit when we export files. Imagine we open foobar.raw and export foobar.txt and foobar.txt.info. But when the application tried to write out foobar.txt.info it hits the 260 character limit in NTFS. Meaning that the original file name was over 255 characters.
