Not sure if this is the right place but:
I have a number of files with the suffix .cost or .tgt and I don't know whether I can delete them or should leave them as I don't know what purpose they have.
examples (from Great Northerner assets) : gsc-flatcar.GeoPcDx.cost, gsc-flatcar.GeoPcDx.cost.tgt, gsc-flatcar.GeoPcDx.tgt

Anyone know what they are for?

I don't know their purpose but I have gotten rid of them in the past with no ill effects.

They're leftovers from the export process. You should be able to delete them all without any issues.

Gentlemen, thank you. I shall do some housekeeping and tidy up.
