There are so much duplicated files in U++ snapshot source...
File list attached.
Many duplicates in U++ source code means certainly bugs and out of date source. Perhaps in 2008 release...
So I went throught the list and found nothing really meaningful or fixable.
There are 3 basic cases:
1 - files that NEED to be duplicate, like Copying file.
2 - 3rd party files.
3 - files in example codes. E.g. same DB schema for several example packages.
