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:

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 |
