I have a lot to go thru, either puzzle thru looking at negs, or scanning all of them to create easily viewable JPG.
When my mom passed away in her home I found a few box's filled with slides, they where in what I guess is called slide holder, a plastic tray that could be loaded into a slide projector.
Most where family photos and a few of them where of me as a child, I bought a nice scanner and slide by slide, the scanner could do 4 or so at a time I scanned about 400 slides.
Due to the way she stored them some where in bad shape, but I scanned all of them anyhow.
When we moved from Plantation to Davie 4 trays disappeared, how I have never figured out, but long after I had a HD failure and that is when I discovered the trays where missing.
That was one of those moments where I wanted to twist my leg around so I could kick my butt for not keeping track of the trays and a backup of that HD.
A lesson learned the hard way.
