Queries file extension visibility state of a file or folder.
Value is 1 if resource should be excluded from backups, 0 otherwise.
This property is only useful for excluding cache and other application support files which are not needed in a backup. Some operations commonly made to user documents will cause this property to be reset to false and so this property should not be used on user documents.

This function requires a native path. Use Path.FileMakerPathToNativePath to convert a FileMaker path to a native path if required. If you like to have the user choose the path, you can use FileDialog functions.
For Server be aware that server has limited permissions and may not be able to access all files on a computer.
