Turns out that the online created folder doesn't show up on my computer because for some reason, it doesn't get checked in the 'selective sync' options by default. So I’m putting this solution at the top here for anyone else who ever runs into this problem. As I was writing a response below, I figured it out. See our troubleshooting page if this icon appears. Usually, this happens because your storage quota is full (can't upload), your hard drive is full (can't download), or you're experiencing connection problems (no Internet). The red circle with the x means that something is wrong, and Dropbox is unable to sync. Dropbox doesn't even see any folder named Documents, never mind not syncing it. Also made sure selective sync wasn't the problem.

I checked Dropbox's documentation as well as running a bad file check. But I don't recall ever having this issue before. so I'm assuming the only issue is the name. If I named it ' Documents' (space first), '_Documents' 'Document' etc, it would sync. If I created a new folder and named it 'Documents' it wouldn't sync. While trying to figure out why, I found that if i renamed the folder, it would sync. So I moved the Documents folder inside the dropbox folder and then symlinked that back to the original location. I wanted to backup my Documents folder with dropbox. (I copied those folders to the HDD with all original permissions, resource forks, etc. For my user folder I put everything on the HDD except the 'library' folder and symlinked them back to the home folder on the SSD. I put the OS/Apps on the SSD and my media on the HDD. I recently setup an SSD/HDD situation in my MBP after removing the optical drive. If I create it on it won't sync to my local machine. If I create it on my local machine, it won't sync to dropbox. This should probably go on the dropbox forums, but they don't seem very active and the people here are very clever, so please bear with me.ĭropbox won't sync any folder called 'Documents'.
