I am copying files from a local drive to Sharepoint Online via a mapped drive.
I have tried Robocopy, drag-n-drop and some trial migrations software(s).
In all cases they cannot properly identify a file that has not changed since it was copied on subsequent copy/sync attempts. At first it was date/time related as the Sharepoint file took the current date/time as opposed to the original date/time.
The migration software trials fixed that by making the Sharepoint file date/time match the original.
My current issue is file size. It any of the products see a different file size they assume the file has changed.
It has not. The file on Sharepoint does not reflect the same size as the original as soon as the copy succeeds.
How can I change that behavior??
