Samsung smart switch transfer application from multiple devices

hello, everyone I am trying to figure out how samsung smart switch backups tansfers photos and videos and documents. Is samsung smart switch copying them ? moving them ? making some kind of intermediate temporary file then copying them ? What is it actually doing ? Because when my brother used samsung smart switch to transfer everything from his many phones -- xiaomi mi max, galaxy s7, LG G3 into a note 8. Alot of files were not discernable from where it came from. Why is that information not organized and lost. And worst of it all, he transferred another duplicate xiaomi mi max phone to the note 8 and now I dont know which files came from the 1st or 2nd xiaomi mi max phone. Both phones are formatted incorrectly and broken. Furthermore, he made a note 8 smart switch backup on the PC with ALL the files from all the previous phones and multiple copies of PC backups of previous phones as well. I am so lost to deal with smart switch and how it transfers and organizes files going from multiple devices.

for example, this folder is a smart switch backup of the s7 to PC local storage C:\

Users\[username]\Documents\Samsung\SmartSwitch\backup\SM-G930W8\SM-G930W8_19999999999\SM-G930W8_20210427130712\Photo\DCIM\Camera

Assuming that this folder is the folder of the galaxy s7 which stores pictures and videos taken with the built-in camera app, how did pictures taken with LG G3 get mixed with pictures taken with the galaxy s7 get in this folder ? I don't see a LG G3 smart switch backup anywhere on my PC or any hard drive in my house. Therefore, if smart switch made a backup of the s7, the s7 must have obtained pictures from the LG G3 in some way. There are no pictures taken with any other device in this folder (apart from the LG G3 and s7). For videos, its even worse, because videos not have exif data doesn't record which device took the video. The naming scheme is the same format for both galaxy phones and LG phones, YYYYMMDD_HHMMSS.jpg, so I don't know which device the videos came from. This is why, samsung smart switch backups must seperate the files taken with the original device from the device it's backing up to. In other words, there must be a new mechanism to identify which pictures/videos originated from the device.

You can see from the following 2 screenshots, that the 2 files are in the same DCIM\Camera folder from 2 devices.

I think that you are trying to do something, that the app simply wasn't designed to do. 

Probably 99% of the people who use Smart Switch to transfer data to a new phone, are only ever transferring from one device.

As I said, you can probably achieve what you want, but it'll involve a lot of manual sorting.

I understand that smart switch is designed to transfer from one device to another but as I've shown above, the timeline is why so many devices get backed up. For example,

Pics/vids taken with device A, no smart switch backup on PC --> smart switch backup to device B --> smart switch backup from device B to device C

Device A -- only device A pics/vids

Device B - will have pics/vids from device A + device B

Device C - will have pics/vids from device A + device B + device C

Do you see ?? there is no separation from the transferred pics/vids to the current device pics/vids
