Description

The settings in TFileDialogOption determine the behavior of a TCustomFileDialog file dialog. TFileDialogOptions is a set of TFileDialogOption. These options are the same as the options for the Microsoft IFileDialog::GetOptions and IFileDialog::SetOptions functions.

The following table lists the possible values:

Value	Meaning
fdoOverWritePrompt	Prompt before overwriting an existing file of the same name when saving a file. This is a default for save dialogs.
fdoStrictFileTypes	The file extension of a saved file being must match the selected file type.
fdoNoChangeDir	Unused.
fdoPickFolders	Choose folders rather than files.
fdoForceFileSystem	Returned items must be file system items.
fdoAllNonStorageItems	Allow users to choose any item in the Shell namespace. This flag cannot be combined with fdoForceFileSystem.
fdoNoValidate	Do not check for situations preventing applications from opening selected files, such as sharing violations or access denied errors.
fdoAllowMultiSelect	Allow selecting multiple items in an open dialog.
fdoPathMustExist	Items returned must be in an existing folder. This is a default.
fdoFileMustExist	Items returned must exist. This is a default value for open dialogs.
fdoCreatePrompt	Prompt for creation if returned item in save dialog does not exist. This does not create the item.
fdoShareAware	For a sharing violation opening a file, call the application back for guidance. This flag is overridden by fdoNoValidate.
fdoNoReadOnlyReturn	Do not return read-only items.
fdoNoTestFileCreate	Do not test creation of returned item from save dialogs. If not set, the calling application must handle errors discovered in the creation test.
fdoHideMRUPlaces	Hide places of recently opened or saved items.
fdoHidePinnedPlaces	Hide pinned places from which users can choose.
fdoNoDereferenceLinks	Shortcuts are not treated as their target items, allowing applications to open .lnk files.
fdoDontAddToRecent	Do not add the item being opened or saved to the list of recent places.
fdoForceShowHidden	Show hidden items.
fdoDefaultNoMiniMode	Open save dialog box in expanded mode in which users can browse folders. Expanded mode is set and unset by clicking the button in the lower-left corner of a save dialog box.
fdoForcePreviewPaneOn	Display the preview pane.
