I had a huge amount of files, over 3600 files, to sync. After waiting for a long time now I have 96 files left to upload. It seems these 96 files are all huge files, for instance, I have a 21GB file. Due to my bad broadband width, I usually pause syncing during the daytime and resume before I go to bed. I wondering what exactly happens in the background when I pause and resume. Let's say, dropbox uploaded 10GB of a 21GB file then I paused and resumed sync. Will it start uploading the whole 21GB file again or just continue the previous uploading and upload the rest portion of the file. Because I am stack with these 96 files.
