Hi! Basically, it's exactly what the title says. It's got nothing to do with the date I uploaded the pictures, but the file names themselves. For example, I've been scanning, cataloguing and organising my mum's old wedding photos (actual photos on paper from 30 years ago) and before I uploaded them, when I saved the scanned files, I gave them chronological order names with the event, date (year-month-day) and then appendix numbers. E.g Mum's wedding 1991-05-26 0001, 0002, etc. But they won't stay in chronological order in the Dropbox folder they're in. I have them in chronological order up to #40. Then it jumps to #100-160 (in chronological order) then goes back to 41, 42 etc (again in chronological order).
My normal digital pics are even worse for this. For example, when I search DSC 025 I get DSC 0250, then DSC 0255, then 0256, then 0252, then 0257, then 0254, then 0251, 0253 and 0259. I just want them in the right order and stay like that. This might be a simple case of setting it to organise by name but I'm unable to do that; I can see group by relevance and last modified when I search and when I got to the specific folder where my mum's wedding pics are it's set to organise by name but I still get that situation of half chronological and half not (those are TIFF files compared to my digital pics being in JPG but not sure that matters)
