Hello Jean-Paul Salaun ,

If there are only a few TU's that you want to discard, simply open the TM - search for the particular TU (s) and delete these- rreatining the good translation

Another option is to search based on different parameters-- maybe for example Last Modified by

If however there is a lot to clean up- you might consider exporting the TM to TMX and using a TMX editor to remove the unwanted TU's and then reimport into a new SDLTM.

A tool that manyuser recommend is I believe 'Olifant'

Thanks Jean-Paul for raising this issue and thanks Steven for your proposal about using Okapi Olifant (it's freeware). Just wanted to confirm that Olifant works like a charm and will do what you require, Jean Paul.
