Consolidating photo libraries from multiple drives

I’m trying out “The Big Mean Folder Machine” version 2.29 to consolidate (or “merge”) various years of photo cruft.  The process of culling and consolidation will hopefully allow me to have a single photo directory backed up to Amazon Glacial forever.  I believe as I mentioned in another post, mechanical disks fail so having a redundant and offsite backup strategy is crucial.  And certainly a key part of of this is limiting the number of places you’re storing your local data so that you can create redundancy.

I’ll write more here when I get all this data and drives sorted out, but so far I was able to run a scan and it the BMFM was able to create a folder hierarchy from multiple drives.   I may need to do some merges first and then a split.
