I am archiving several large project folders to dropbox using the odrive app. I have folders with many subfolders that contain lots of different file types. I found that several folders were not able to completely sync. When looked down through the tree, I found files that had a size of 0k that were the problem. Only way to deal with it was to close odrive and search for the files by size:empty - delete then restart odrive
