When Final Cut Express Reconnects Your Clips
In certain circumstances, Final Cut Express checks to make sure all of the media files that
correspond to clips in your project have not been modified, and that none of the media
files are missing. Final Cut Express checks for offline clips in the following situations:
 When you open a project file: If Final Cut Express detects missing media files that weren’t
missing the last time you saved this project, the Offline Files window appears.
 When you switch from any application to Final Cut Express: If you switch from your
project in Final Cut Express to the Finder (or any other application) and modify your
media files, Final Cut Express detects these media file modifications when you switch
back. In this case, the Offline Files window appears when you switch back to
Final Cut Express.
About the Offline Files Dialog
The Offline Files dialog appears each time you open a project whose clips’ media files
have been modified in any way. This dialog may also appear when you switch to
another application and then return to Final Cut Express. If any media files are
modified, moved, or deleted during this time, you see the Offline Files dialog.
You can select which
media files to disregard.
