Return value

Remarks

Notifications are sent in response to calling one of the following methods for importing a file system.

UpdateImport method receives import notifications from ISO9660, Joliet and UDF file systems. A notification is sent:
  • Once after every individual imported file.
  • Once before every directory import begins.
The totalFileItems parameter of an UpdateImport event is always set to (-1) for ISO9660 and Joliet file systems, because of the difficulty quickly and accurately determining the total number of files in an ISO9660/Joliet file system prior to import.

Import notifications are generated only for files and directories, and not for associated named streams.

If the currentItem is a directory, it contains a back slash '' at the end.
