names of folders in iphone storage

I am just wondering if anyone can tell me what the letters mean at the end of folder names?


I understand that a folder named "202011_" contains photos from the year 2020 and the month of November... but then for SOME of my folders they will say "202011_a" and "202011_b"


These folders generally will have less photos in them, and quite often there will be doubles of just a few of the photos that were in the original "202011_" folder.


My first guess was that perhaps these are photos that i have edited? But that doesn't seem to hold true all of the time. Can anyone shed any light?

iPhone 8 Plus, iOS 13

If you are viewing the iPhone storage with Windows what you see is really meaningless. Apple changes folder names regularly because they don’t expect anyone to look at them. You apparently have iOS 13. The folder names are completely different in iOS 14, and different again in iOS 15. Here is how you should be accessing photos→Copying personal photos and videos from iPhone, iPad, or iPod touch to your computer

The folder names are not meaningless - in that they correspond to the year and month they were taken in, I’m really just asking if anyone know what the “sub-folder” letter corresponds to: currently it seems that the sub folder has the year, the month taken, and then a letter (starting from a) and there will sometimes be one or two sub folders alongside an “original” folder. So there clearly must be a system, so I wondered if anyone knew what that system was for my current iOS (which is 16.3.1, I’m not sure why my original post shows as iOS 13 sorry)


The link you gave explains the exact process I am already using of importing photos via windows…
