I had boxes and boxes of old drives that I wanted to get organized which drove that feature: https://photostructure.com/about/introducing-photostructure/...

It's also why I implemented bitrot detection and metadata inference. A beta tester just called the date parsing heuristics "freaking awesome and so close to black magic…" :)

(And if you prefer the command line, know you can do tons of things via the CLI: https://photostructure.com/server/tools/ )

Hey, PhotoStructure looks amazing. I'm intrigued. How and when does bitrot detection work? I couldn't find it on your site. I spend a decent amount of time making PAR2 volumes so I can detect failures as I've not come up with a better idea.

The bitrot detection is via libjpeg, libraw, and ffmpeg (to handle both photo and video validation): they can be run in verbose modes that can report decoding errors which are due to file truncation or outright corruption.

Wow - this sounds amazing. How does one set it up; does it automatically occur?

Yeah, it's part of automatic organization:

How do you compute the duplicates? Does it detect rotated dupes, and resolution differences?

I tried a few things with ImageMagick, but ran into problems. I'll have to try your app!
