FreeFileSync vs Karen's Replicator Comments


- FreeFileSync is Freemium and Open Source
- FreeFileSync is Lightweight and Privacy focused








































































easier to configure - but requires directory locking and other items. Karen's Replicator when it has errors, some of them do not make sense unless the software is dated to not be able to handle certain path lengths or other changes that have been made to keep the software up to date - but can't since Karen passed away. It's a shame because thats amazing software that the source code could be continued and a few changes would instantly create a top dog.
