Diff sync with PowerPoint

New Contributor

Hi, as far as I understand, diff sync for none-office files are delayed. But office files should work with "delta" right now? Or not? How is diff sync is working now?

Hi @Aleks_Puig

Currently marked as rolling out for all file types: see the Microsoft 365 roadmap, last updated 3/26/2020

https://www.microsoft.com/en-us/microsoft-365/roadmap?filters=&searchterms=33412

As you say, before this the new office file types were supported: .docx, .pptx, .xlsx. Onenote files are excluded

The documentation hasn't been updated yet, so it's unclear on the status.

Hope that answers your question

Hi @Christopher Hoard ,

So basically if I have 1 gb Power Point presentation in .pptx format, and add 1 blank slide, then OneDrive should sync only this blank slide?

Correct, see here

A 1 Gigabyte file would have to be transferred in full whenever it was changed even if the entire changes made up a single Kilobyte only. Differential synchronization addresses the issue by syncing only the changed bits of a file and not the file in its entirety

Hope that answers your question

@Christopher Hoard no, i've got it :)

That it should be transferred initially.

But after changes, how will onedrive works now and after diff sync?
