Adding and updating commands add be combined with the -ExitWhenDone (-ewd) key. In that case, WinCatalog will be closed after an operation is complete. The key can be combined only with -AddNew (-add) or -Update (-u) commands:
Start Wincatal, open the catalog file "d:\my catalog.w3cat", update the folder (or the disk) "Catalog\Folder\Sub Folder\My Music", exit WinCatalog when the operation is complete.
