Just when you think all is well, Google Drive surprises you with a lost and found upload error. To be exact the files were upload and there was an issue by which Google Drive decided to not stop uploading and leave the files as is within their current folder but rather move them to a lost and found folder. This lost and found folder collects all files from all folders that failed to upload. You can see where the problem starts and gets more complicated depending on the number of folders there are.
In this video I review this error and what to do both in the situation or in preparation for it.
