Computer A and Computer B are both syncing a given folder. You add a 2GB file to the folder on Computer A, naturally it gets pushed over the wire to Computer B, albeit slowly. If you then make changes to the 2GB file on computer A, what happens?
I figure the choices are really
a) it pushes the entire 2GB file to Computer B or b) it analyzes the differences between the two files, and sends only the changes over the wire. Computer B's mesh service then applies those changes.
But which is it?
Also, what happens if I move that 2GB file to a subfolder?
5Wonderfully written. However, I think the question was more about what does the Windows Live Mesh product do. – Chris_K – 2011-05-28T01:05:12.883
1I did some testing and you're right on both counts. Based on how quickly Mesh returned to "Up To Date" status, there is definitely some kind of differential sent between machines and not the entire file. Also, when moving files I confirmed that the originals were deleted and new files added to the new folder. – Ken Pespisa – 2011-05-28T13:10:23.583
1One other fun fact. I moved around 150+ 100MB files from Computer A into a new folder, and after doing so noticed Mesh was slowly chugging through the list on Computer B, re-downloading them as if they were new (after having deleted the files from the original folder). I saved a lot of extra bandwidth drain by moving those files out of the recycle bin on Computer B and into the correct folder. Mesh intelligently detected the change, scanned the folder again, and then showed it as Up-To-Date. – Ken Pespisa – 2011-05-30T00:28:02.377
