You will need to update NVivo when you change the location of media files not embedded within the project. You can see which audio/video sources have media files stored externally by clicking on All Sources Not Embedded in Navigation View.
In List View, select the audio or video source you want to update.
On the Project menu, click Update File Location.
The Update File Location dialog box is displayed.
Use the Look in drop-down list to find the new Windows location.
Select the required audio or video file.
Click the Open button.
NVivo checks that the audio or video file has the same content as the original file.
If you have moved a number of media files to a new directory:
In Navigation View, click the All Sources Not Embedded folder.
In List View, select the required files.
On the Project menu, click Update File Location.
The Browse for Folder dialog box is displayed.
Click the required folder.
Click OK.
NVivo checks that the audio/video files in the new directory have the same name and content as the original files.
