Constants

 
FOS_OVERWRITEPROMPT
Value: 0x2
When saving a file, prompt before overwriting an existing file of the same name. This is a default value for the Save dialog.
FOS_STRICTFILETYPES
Value: 0x4
In the Save dialog, only allow the user to choose a file that has one of the file name extensions specified through IFileDialog::SetFileTypes.
FOS_NOCHANGEDIR
Value: 0x8
Don't change the current working directory.
FOS_PICKFOLDERS
Value: 0x20
Present an Open dialog that offers a choice of folders rather than files.
FOS_FORCEFILESYSTEM
Value: 0x40
Ensures that returned items are file system items (SFGAO_FILESYSTEM). Note that this does not apply to items returned by IFileDialog::GetCurrentSelection.
FOS_ALLNONSTORAGEITEMS
Value: 0x80
Enables the user to choose any item in the Shell namespace, not just those with SFGAO_STREAM or SFAGO_FILESYSTEM attributes. This flag cannot be combined with FOS_FORCEFILESYSTEM.
FOS_NOVALIDATE
Value: 0x100
Do not check for situations that would prevent an application from opening the selected file, such as sharing violations or access denied errors.
FOS_ALLOWMULTISELECT
Value: 0x200
Enables the user to select multiple items in the open dialog. Note that when this flag is set, the IFileOpenDialog interface must be used to retrieve those items.
FOS_PATHMUSTEXIST
Value: 0x800
The item returned must be in an existing folder. This is a default value.
FOS_FILEMUSTEXIST
Value: 0x1000
The item returned must exist. This is a default value for the Open dialog.
FOS_CREATEPROMPT
Value: 0x2000
Prompt for creation if the item returned in the open dialog does not exist. Note that this does not actually create the item.
FOS_SHAREAWARE
Value: 0x4000
In the case of a sharing violation when an application is opening a file, call the application back through OnShareViolation for guidance. This flag is overridden by FOS_NOVALIDATE.
FOS_NOREADONLYRETURN
Value: 0x8000
Do not return read-only items. This is a default value for the Save dialog.
FOS_NOTESTFILECREATE
Value: 0x10000
Do not test whether creation of the item as specified in the Save dialog will be successful. If this flag is not set, the calling application must handle errors, such as denial of access, discovered when the item is created.
FOS_HIDEMRUPLACES
Value: 0x20000
Hide the list of places from which the user has recently opened or saved items. This value is not supported as of Windows 7.
FOS_HIDEPINNEDPLACES
Value: 0x40000
Hide items shown by default in the view's navigation pane. This flag is often used in conjunction with the IFileDialog::AddPlace method, to hide standard locations and replace them with custom locations.

Windows 7 and later. Hide all of the standard namespace locations (such as Favorites, Libraries, Computer, and Network) shown in the navigation pane.

Windows Vista. Hide the contents of the Favorite Links tree in the navigation pane. Note that the category itself is still displayed, but shown as empty.
FOS_NODEREFERENCELINKS
Value: 0x100000
Shortcuts should not be treated as their target items. This allows an application to open a .lnk file rather than what that file is a shortcut to.
FOS_OKBUTTONNEEDSINTERACTION
Value: 0x200000
The OK button will be disabled until the user navigates the view or edits the filename (if applicable). Note: Disabling of the OK button does not prevent the dialog from being submitted by the Enter key.
FOS_DONTADDTORECENT
Value: 0x2000000
Do not add the item being opened or saved to the recent documents list (SHAddToRecentDocs).
FOS_FORCESHOWHIDDEN
Value: 0x10000000
Include hidden and system items.
FOS_DEFAULTNOMINIMODE
Value: 0x20000000
Indicates to the Save As dialog box that it should open in expanded mode. Expanded mode is the mode that is set and unset by clicking the button in the lower-left corner of the Save As dialog box that switches between Browse Folders and Hide Folders when clicked. This value is not supported as of Windows 7.
FOS_FORCEPREVIEWPANEON
Value: 0x40000000
Indicates to the Open dialog box that the preview pane should always be displayed.
FOS_SUPPORTSTREAMABLEITEMS
Value: 0x80000000
Indicates that the caller is opening a file as a stream (BHID_Stream), so there is no need to download that file.
