3-way comparison - an EFU task?

Post by dglp » Thu Jan 03, 2019 12:19 am

I've got at least 3 drives with copies of several thousand jpgs, and I want to rationalize the bunch.

I could compare Drive A with Drive B, generate a list of common files, then compare A with C, and B with C, then filter for all the common files. Then there's Drive D, and perhaps E.

But what I'd like to do is generate a single file list from all the drives, and use that list as a reference for Everything to search from.

There's another way of doing this, but it is so massive as to be ugly and a time suck. I could make a single Boolean string of all the file names. "0004613.jpg"|"0004614.jpg"|"0004616.jpg"|"0004624.jpg"|"0004630.jpg"|"0004638.jpg" and so on, for 7000 files.

Do you really want me top do that? :lol:

Now, I understand that EFU is effectively an index stored locally, and comes in handy when one wants to figure out which file might be on a disconnected drive. So it does not seem suited to the task of simply providing file names to locate across multiple drives.

But can the EFU be adapted to the task I have? Or is there another way to provide a search list?
