This is fairly brute force and rough, but there are quite a few old
files in there, helps a bit with versioning and readfile code testing.
Note: Five files are currently excluded since failing in debug builds
at least, most of the time for memleaks issues. The two other 'errors'
may also not be actual issues, but this needs to be investigated further.
Also, in the future, when time allows, it may be better to generate a
set of dedicated testing files, with as many official releases versions
as possible?
