Overloads

GetFoldersAsync(CommonFolderQuery)

Retrieves a list of folders and file groups based on a specified folder query. This returns a snapshot of the folders or file groups at a point in time and does not allow you to keep track of changes through events.
GetFoldersAsync(CommonFolderQuery, UInt32, UInt32)

Asynchronously retrieves a range of folders in this folder based on a folder query. This returns a snapshot of the folders or file groups at a point in time and does not allow you to keep track of changes through events.

Parameters

query
CommonFolderQuery

The type of folder query to perform.

Returns

IAsyncOperation<IVectorView<StorageFolder>>

IAsyncOperation<IReadOnlyList<StorageFolder>>

Parameters

query
CommonFolderQuery

The type of folder query to perform.

startIndex
UInt32

unsigned int

uint32_t

The zero-based index of the first folder or file group in the range. This parameter defaults to 0.

maxItemsToRetrieve
UInt32

unsigned int

uint32_t

The maximum number of folders or file groups to retrieve. Use -1 to retrieve all folders or file groups.

Returns

IAsyncOperation<IVectorView<StorageFolder>>

IAsyncOperation<IReadOnlyList<StorageFolder>>

When this method completes successfully, it returns a list (type IVectorView) of folders of file groups that are represented by StorageFolder objects.

Attributes
OverloadAttribute RemoteAsyncAttribute

Remarks

Use this overload to retrieve improve system performance by presenting a virtual view of the query results that includes only the necessary subset of folders.
