I understand how to get the subfolders and files synced, but the UI is misleading and confusing. Whenever I double click to open a folder in odrive on my Mac, the folder gets a blue checkmark, but the subfolders and files are not synced. Simply remove the backslash from your folder and file names to get Dropbox to synchronize them again.I have an Amazon Cloud drive with a couple of main folders and tons of subfolders, with thousands of photos in those subfolders. Still, a backslash breaks Dropbox syncing. Backslash is the cause that certain files won’t sync in Dropbox You can use a backward slash in the Finder though. That’s why even today in Mac OS X you can’t use – for example – a forward slash in a file name or folder name. To understand why this struck me, you must know a little bit about OS X’s roots. Traditionally, in *NIX systems, punctuation like slashes and colons were often reserved for specific tasks and therefore called ‘special characters’. Then I found out that all files were in a folder with a backslash in the name. If all this is not the problem, they mention that you can use OS X Terminal to change the HFS+ system file flags, with the command chflags nouchg filename.īut even that didn’t make the red dot go away on my files. This can happen if you changed the system account name. Check whether the file permissions are set to a different user.

Check whether your are using a proxy that is not configured for Dropbox.Check that your computer can’t get a secure connection.Check that your computers system time is off.Check that there is no anti-virus software getting in the way.Disconnect and reconnect your desktop Dropbox application.According to, this means they can’t be synchronized by Dropbox. All other files in the Dropbox folder were synced just fine. One day I discovered that certain files and folders in my Dropbox folder had a red circle with an ‘x’ in it on their icons.
