Unexpected EF Behavior

I’m updating a set of mboxes nightly. Some of them change, but many don’t. When I reimport into EF (using the Import Files… menu item) , it correctly notes the ones that haven’t changed are duplicates, but then appears to rebuild them and reindex them anyway. Is there a way to get it to just pass over the ones that haven’t changed?

The ones that are noted as duplicates are not imported, so EagleFiler won’t rebuild or reindex them—they’re not even in the library. Perhaps you’re seeing it working on other mailbox files.

Thanks. Operator error confirmed.
