// this is a hidden preference setting, see bugzilla bug 80035
// (http://bugzilla.mozilla.org/show_bug.cgi?id=80035)
//
// the default value for this setting is true which means when migrating from
// Netscape 4.x, mozilla will copy all the contents of Local Folders and Imap
// Folder to the newly created subfolders of migrated mozilla profile
// when this value is set to false, mozilla will not copy these contents and
// still share them with Netscape 4.x
//
// Advantages of forbidding copy operation:
//     reduce the disk usage
//     quick migration
// Disadvantage of forbidding copy operation:
//     without perfect lock mechamism, there is possibility of data corruption
