What is a METADATA_NEVER_INDEX file?
A METADATA_NEVER_INDEX file is a hidden file created on hard drives, flash drives, iPods, and other volumes used with Mac OS X. It prevents Spotlight, Apple's built-in search tool, from indexing a directory or an entire volume.
METADATA_NEVER_INDEX files are blanks file that are not meant to be opened by the user. However, if you need to find them, they are typically located in the root directory, or top level of a disk. If you remove the file it may allow the folder or volume to be indexed by Spotlight on Mac OS X systems.
