Abstract: A cloud computing system can be used to transparently reduce the storage space of an application on a client device. An application can be installed with a minimal set of application resource files. The remaining application resource files can be replaced with application resource file placeholders, which can have the appearance of application resource files but are in fact empty files. When an application requests an application resource file, an application resource file retrieval process installed on the client device can detect the difference between an application resource file and an application resource file placeholder. The application resource file retrieval process can trigger a fault in response to detecting an application resource file placeholder, which causes the client device to obtain the requested application resource file from a remote storage location, such as cloud-based storage. Additionally, installed application resource files can be replaced with application resource file placeholders.

Abstract: Systems, methods, and non-transitory computer-readable storage media for updating software applications installed on client computing devices, creating a manifest file describing the differences between multiple versions of application archives present in an application distribution system, and coordinating an update process for updating the applications on the client computing devices are disclosed. A scheme of hard-linking to existing files, downloading new files, and erasing unwanted files can be used.

Abstract: Methods and systems for creating and using data structures for operating systems. In one embodiment, a method includes receiving information indicating that a first installer is being launched for a first application program and storing, in response to the receiving of the information, first data which specifies changes to an operating system (OS) data structure that is used to configure a system to allow execution of the first application program after installing the first application program, the first data being stored separately from the OS data structure. The OS data structure may be, in one embodiment, a registry for configuring a system to execute multiple applications on the system.

Abstract: A virtual installation process and supporting environment. The virtual installation process may be considered a two-stage installation process. In the first stage a pseudo-installation may occur in which a user is provided an installation experience by a virtual installation environment that stores changes to be made as a result of the installation process. In the second stage of the installation process, the changes that were previously stored may be made to the host system. These changes may include changes to the registry, filesystem and/or any other host system components. The second stage may be initiated by a user attempting to launch the application for the first time. Other triggers may also be supported.

Abstract: A path request is generated by a secondary platform application, such as a word processor, and is received by invention. The path request may contain the location of a library required for the application to function, or a document saved previously by a user. The path request comprises a complete path for the requested file. The complete path is formatted for a file system and file structure for expected by the application. The elements of the path request, such as directories, disks, filenames, file types, etc. are analyzed by the invention in order to provide another complete path. The path provided by the invention is formatted for a different file system and file structure. The file pointed to by the path provided for the invention enables the secondary platform application to find and use the requested file.

Abstract: A cloud computing system can be used to facilitate data item sharing and collaboration among groups of users through the creation and management of collections. A group of users, each of which is associated with at least one client device, can subscribe to a collection. A subscribed user can create a data item locally on a client device and assign the data item to a collection. In response to the assignment, each user subscribed to the collection can receive and store a copy of the data item locally on a client device. Any modifications made to a local copy of the data item can automatically be distributed to each subscribed user's client device. The modifications, including conflicting modifications, can be merged into the local copy.

Abstract: A digital rights management system permits an application owner to cause code to be injected into the application's run-time instruction stream so as to restrict execution of that application to specific hardware platforms. In a first phase, an authorizing entity (e.g., an application owner or platform manufacturer) authorizes one or more applications to execute on a given hardware platform. Later, during application run-time, code is injected that performs periodic checks to determine if the application continues to run on the previously authorized hardware platform. If a periodic check fails, at least part of the application's execution string is terminated—effectively rendering the application non-usable. The periodic check is transparent to the user and difficult to circumvent.
