OneDrive's differential sync doesn't work
OneDrive's differential sync doesn't work; instead, it updates the whole files when there's a change in a file.
The issue happened on two of my computers. Both are running Windows 11, and the OneDrive version is 26.074.0420.0001.
This is how the bug happens:
Using Acrobat to open a PDF file that's saved in the OneDrive folder in File Explorer, then edit the PDF and save it. Then I saw the OneDrive panel on the right of the taskbar showed it was uploading the whole file (because it uploaded the same file size as my file size) to the cloud, not just the changes.
Differential sync used to work well on PDF files on my computer, but I don't know why it stopped working.
I've tried resetting OneDrive using the command %localappdata%\Microsoft\OneDrive\onedrive.exe /reset, but it doesn't work.
And I've searched for solutions on the internet, but I got no valuable information.
Please help me.
