Arguments

eobject

An object with the following properties:

arrayarray: An array containing the list of orphaned files that will be deleted.

Description

Discussion

The beforeDeleteOprhanMediaFiles event is triggered before any orphaned files on the device file system are removed. Orphaned media files are files that were previously downloaded but are no longer referenced by any record in a List.

If this event returns false, the orphaned files will not be deleted.

Example

var childList = {dialog.object}.getControl('CHILD_LIST');
if(childList && childList.listIsDirty()) { 
    // Don't delete orphaned media files if the 
    // child list contains unsaved edits.
    return false;
}
