Symptom
An alert box appears with this message:
"The burn cannot proceed because the disc contains filenames that could not be converted."
You then have the option to save or discard the image file.
Solution
This issue may occur if there are files or folders with nothing but spaces or tab characters in their filenames. You should remove or rename these files or folders in order to burn the disc.
The most common source of file or folder names consisting only of tabs or spaces are folder picts. Folder picts are a series of folders with custom icons arranged in a way to create a picture in a Finder window. See Figure 1 below for examples of folder picts.
