I am transferring files between hard drives and comparing them with DeltaWalker (a byte for byte comparison tool) to be sure nothing was lost during the transfer. DeltaWalker shows ".lrt" folders that are not normally visible in the Finder. What are these folders and can they be deleted to save space?

Thank you.

Those folders hold the LRTimelapse previews, some sequence settings and snapshots. If you delete them, LRTimelapse will have to regenerate the previews for those sequences, this will not harm but take some time. If you work with snapshots, they will be gone when you delete those folders.

Thank you very much!
