I was wondering if anyone could help. I have a tab file in MapInfo consisting of just polylines. Each is meant to have its own reference number, however some are duplicated (e.g two lines occupying the same position with the same ID's) I can identify these with a query, but what I need to know is if it's possible to delete duplicates and leave one remaining (it doesn't matter which one as they are identical).
(ps. I also have access to QGIS if it is easier in that)
