By this property if you want to check file has been removed ,deleted from physical path then this will be true and you can check like if you have a tree view and you dont want to repopulate your tree view then use filesystemwatcher and repopulate the tree only when files have been changed,delete or rename. or you can throw a messagebox like above.

Raymond Chen, a popular Microsoft blogger, recommends that you not worry about leaving keys because it's per-user data anyway and in many environments it's preferable to leave it behind. Definitely do not try to enumerate all user profiles to remove the keys for the other users because in the case of roaming profiles you'll likely corrupt a lot of stuff. If you want to remove all traces of your program, one alternative is to write your own SHMessageBoxCheck dialog and store the preference wherever you want.
