Hello, everyone.
I'm a Korean user. I'm sorry. I don't know English, so I use a translator, so sentences can be awkward.
If you save photos taken with your iPhone 12 to your PC via drop box auto sync,
they look normal on your local PC, but if you upload them to Synology NAS, they will corrupt your files.
When I upload a picture to the NAS like the picture on the right,
the file of the same name already exists in 0bite state,
and an error appears like the picture on the left, so I ask if I want to overwrite it.
Some photo files succeed when you move from the drop box, while others fail.
Please Help me.
