How do I merge TMs with only the newest instance of each duplicate entry remaining?
Thread poster: lhipsher

I reference this forum quite a bit and have found a lot of helpful advice so I'm hoping someone can help me with this problem.

I am wondering if it is possible to merge 2 TMs while maintaining the newest instance of each duplicate entry instead of simply overwriting one TM with the other.

It seems Olifant might be the best program to do this. I tried updating the Merge Options to overwrite the 'ChgDate' Field but I can't figure out how to only overwrite with newer duplicates and exclude older. Any assistance that someone could give me would be much appreciated!

Thanks in advance!

An easy way to do this is to:

1. Merge the two TMXs with Heartsome's free TMX editor (File > Merge TMX…)
2. Run the commend: Edit > Clean up TM… and makes sure ‘Repetitions (keep the latest segment)’ is selected.

This will get rid of all the oldest versions of any duplicate entries.

Repetitions (keep the latest segment)


PS: Heartsome's TMX editor used to be a paid program, but they recently went bust or decided to call it a day. The open source version can be downloaded here:
