This might come in handy for people using owncloud or Dropbox that want their files to occur in the cloud and somewhere on their machine. If you want to make a certain directory path see files in the actual location they exist, run the following with Terminal.app:

ln -s path/where/files/really/exist path/you/wish/would/work

If you’re doing this with Owncloud or Dropbox, the first file path should be the directory path of your Dropbox account and the second directory path should be where you want your files to appear.
