摘要： The subject disclosure is directed towards transforming a file having at least one undeduplicated portion into a fully deduplicated file. For each of the at least one undeduplicated portion, a deduplication mechanism defines at least one chunk between file offsets associated with the at least one undeduplicated portion. Chunk boundaries associated with the at least one chunk are stored within deduplication metadata. The deduplication mechanism aligns the at least one chunk with chunk boundaries of at least one deduplicated portion of the file. Then, the at least one chunk is committed to a chunk store.

摘要： The subject disclosure is directed towards changing a file from a fully deduplicated state to a partially deduplicated state in which some of the file data is deduplicated in a chunk store, and some is recalled into the file, that is, in the file's storage volume. A partial recall mechanism such as in a file system filter tracks (e.g., via a bitmap in a file reparse point) whether file data is maintained in the chunk store or has been recalled to the file. Data is recalled from the chunk store as needed, and committed (e.g., flushed) to the file. Also described is efficiently returning the file to a fully deduplicated state by using the tracking information to determine which parts of the file are already deduplicated into the chunk store so as to avoid their further deduplication processing.

摘要： Navigational functionality is abstracted from user interface pages associated with a wizard and allocated to a navigation module. The navigation module provides a hierarchical tree of nodes representative of the user interface pages in the wizard. In operation, a token is transmitted from a user interface page to the navigation module when a user activates a user interface control within the user interface pages. The token instructs the navigation module to traverse the hierarchical tree to determine a successor page to present to the user, such as a next user interface page, a previous user interface page, a user interface page defining a selected branch, and so on. Abstracting navigational information from individual user interface pages is advantageous because it simplifies the design and modification of user interface pages, as well as promotes the modularity and portability of the user interface pages.
