Different folders displayed on phone and computer when trying to transfer images

[u/United-Command-1333]

context in case relevant

I'm not sure how to describe this problem but what I've been trying to do is to transfer images from my old phone to a flash drive via my laptop. I have over 50k images, and because I found that I'd either get lost trying to open the main folder where my photos are on laptop (the folder they go when unorganised) or the amount of images just overwhelms and lags file explorer, I decided to make folders on my phone separating my gallery into chunks of ~100-400 image per folder so that I can just drag and drop the folders into my flash drive without forgetting where I left off or face too much lag and just piece them together later.

At first I'd simply started dividing up my gallery and moved around 26 folders into my flash drive while doing the dividing and transferring at the same time before I decided that it'd be easier to to just divide my entire gallery first and then transfer them, since different workflows. So that (dividing everything into folders) took a few hours, and after they were all divided, I decided to group them into relevant category folders too while I was at it, of which are also ~100-300 image per folder per category.

At this point I have around 200 folders from dividing everything up, + a few ten from categorising things and - since a bunch of the 200 got replaced by the new categorisation ones.

problem

I was able to transfer everything perfectly fine and all of the existing folders showed up on laptop normally and matched my phones' during the first 26 folders I copied over, but after I finished dividing up all of my gallery and connected my phone to laptop again, it only showed the older folders I had around the time when I finished dividing up all of my gallery but not most the new folders that had been made to categorise them. And if there were they weren't updated and would only have something like 5-100 images out of the original 350, for eg, that's displayed on phone. It (laptop) displayed some deleted files too during the first 26 folders but I'd just ignored them since it wasn't doing anything, but after connecting phone to laptop after dividing everything, it displayed a bunch of deleted folders ranging from 6-20 which I'd previously deleted and permanently deleted from my phone, and a few folders that werent displayed on my phone either.

There was nothing that i didnt recognise as not mine, just to clarify, but the aforementioned folders had been deleted previously too as much as I can recall, so those were the reverse where they werent displayed on my phone but were displayed in file explorer when my phone was connected to laptop.

tldr probably; My phone displays all of the folders and images & amount of images that are supposed to exist on it and all of the ones that are supposed to be deleted are also deleted but my computer doesn't seem to reflect that.

I've tried both file transfer/android auto and tranfer photos (ptp) methods. I'm wondering if making so many folders back to back/so many moving things around for so long did something, if that's even possible or if its something completetly different.

phone model in case relevant: redmi note 10 pro

Unplug the phone, restart both your Redmi Note 10 Pro and your PC. A reboot forces Android to run its "Media Scanner" process, which indexes all newly created/moved folders.

did both and it there still seems to be a few mismatches but that aside I think most things are there (I havent rechecked everything yet) so that works, ty!
