OK, the problem I have is that all of our chromatograms come in as ABI
files.  I am trying to encourage more people to use these in their
assemblies.  Given our disk space limitations it would make sense for
people to convert to SCF/ZTR format and work with those - however our
experience is that if we do that, then people never go back and delete
the ABI files, and just end up with two copies of everything!  In this
case it would be better not to convert the files in the first place, as
at least that would save a bit of space.

However, now I think about it, a better solution might be to have an
option in the Format conversion module which would delete the original
chromatogram file upon successful conversion to SCF/ZTR format.  This
would both reduce clutter, and save on disk space, and would mean that
we end up with a friendly file format.  If you are converting files, I
can't see many occasions under which you need to keep the originals as
well (as long as the conversion was successful).

Do others think this would be useful - or am I on my own here? :-)
