Disclosed are systems, methods, and non-transitory computer-readable storage media for migrating content items from a source user account to a target user account. A user can specify content items in the source user account to be migrated to an existing or new target user account. A new content entry including an account identifier of the target account and a pointer to the content item can be created for each migrated content item. Further, a determination can be made as to whether a sharing link to each content item exists, and if so, the content pointer of the old content entry is modified to forward or redirect to the new content entry. An active flag associated with the old content entry can be set to false or 0 to indicate that the old content entry is no longer active.

Migrating content items

The speed at which files can be accessed from a remote location is increased by predicting the file access pattern based on a predictive model. The file access pattern describes the order in which blocks of data for a given file type are read by a given application. From aggregated data across many file accesses, one or more predictive models of access patterns can be built. A predictive model takes as input the application requesting the file access and the file type being requested, and outputs information describing an order of data blocks for transmitting the file to the requesting application. Accordingly, when a server receives a request for a file from an application, the server uses the predictive model to determine the order that the application is most likely to use the data blocks of the file. The data is then transmitted in that order to the client device.

Predictive models of file access patterns by application and file type

Users specify that a file set comprising their files, folders, or other content owned by the users should be made accessible via a link, such as a uniform resource locator (URL). The system which stores and provides access to the files accordingly creates a link that specifies the file set to be made accessible. The users may distribute the link to recipients with whom the file set is to be shared, and the distribution may be performed in any manner that the users choose.

File sharing via link generation

A user interface (e.g., a browser window) includes a display area for displaying an image (e.g., a book page image). The image can be rescaled based on the dimensions of the display area and other factors. In some implementations, margins in book page images are adjusted to create additional or less display area.

Adjusting margins in book page images

A user interface (e.g., a browser window) includes a display area for displaying an image (e.g., a book page image). The image can be rescaled based on the dimensions of the display area, one or more attributes of the image and other factors. In some implementations, a sequence of images are searched for a table of contents. If a table of contents does not exist, one is created by searching the images for white space and/or other attributes that can be used to determined entries in the table of contents. The entries in the table of contents can be hypertext links.

Recognizing table of contents in an image sequence

A user interface (e.g., a browser window) includes a display area for displaying a content reference page. In some implementations, a content reference page is generated that includes information related to content. The content reference page includes sections for presenting keywords found in the content, reviews of the content, portions of content that are of interest to a user (or a class of users) and other useful references, etc.
