Dropbox unable to sync folders but said folders don't exist when I try to access them.

Hello DavidAJDavies 

This issue is caused by three hidden junction folders called "My Music", "My Pictures" and "My Videos" which are located in your C:\Users\Your_Username\Documents folder.  The permissions issue message is misleading. This is not a permissions issue. The real issue is that those folders are junction folders, which Dropbox doesn't sync. Those folders being hidden also explains why you cannot locate them easily in Windows Explorer.

The good news is those hidden junction folders are only there for backwards compatibility reasons, but usually can be removed without any issues.

Here is how to fix this:

1. Open a Windows command prompt

2. The command prompt usually opens in your home folder (C:\Users\Your_Username) as its current directory so to get to your Documents folder you just type :

cd Documents

3. You should now have your command prompt switched to the "Documents" folder as its current directory. In there you can check for the existence of those three junction folders using this command:

dir /a:h

3. Then to remove those three folders you will use the following commands:

rmdir "My Music"

rmdir "My Pictures"

rmdir "My Videos"

4. Once those hidden junction folders are removed, you can restart Dropbox and it should no longer complain about them anymore.

Hope this helps.
