Systems and methods for displaying a view of a virtual file system through a file viewer of a computer operating system are described herein. In an embodiment, an application receives a request to return data to display in a view of a file repository from a service of a computer operating system which is configured to cause displaying of the view of the file repository. The application accesses stored configuration information which identifies one or more particular queries which are mapped to a particular folder of the file repository. The application transmits the one or more particular queries to a database management system and receives structured data that satisfies the one or more particular queries in response. The application returns the structured data to the service of the computer operating system to cause the service to display, in the view of the file repository, the particular folder and a view of one or more files in the particular folder comprising the structured data that satisfies the one or more particular queries.

Systems, methods, and other embodiments associated with controlling a device to perform functions using features of a native file system are described. According to one embodiment, a method includes in response to receiving a request to a file system in a first device from a second device, decoding a file path in the request to determine a function of the first device that correlates with the file path. The file system is defined to include a hierarchy of folders that correlate with functions performable by the first device. The method includes causing the first device to perform the function associated with the file path decoded from the request.

Systems, methods, and media file system virtualization. Exemplary methods may include rendering a sparse file system and creating a block map for the sparse file system. The block map may include a map record for each file record included in the sparse file system. A map record may include extents for blocks associated with a file record, the map record providing a mapping between allocated block sectors for a file record in the sparse file system and corresponding blocks associated with one or more data sources.

Media, methods and systems are provided for interfacing a mobile device to an application virtual machine via an application programming interface (API). A first set of file connection properties for one or more internal storage locations and a second set of file connection properties for one or more external storage locations are defined at a mobile device. The first and second sets of file connection properties define the file storage locations for a plurality of media types. Requests are received from the application virtual machine for the first and second sets of file connection properties. The application virtual machine identifies a current default storage area that can be selected from the one or more internal storage locations and the one or more external storage locations, and indicates whether the current default storage location is an internal storage location or an external storage location.

Systems and methods for overlay-based file tagging using virtual file systems. An example method may include: receiving, from a file system client, a request to perform a file operation with respect to a file; identifying a part of the file name representing a mount point of a virtual file system associated with the file; identifying a memory pointer associated with the mount point; identifying, using the memory pointer, an instance of a class implementing the virtual file system; retrieving the metadata associated with a file using a memory data structure associated with the instance of the class, the memory data structure comprising a plurality of records, each record associating a file identifier with a metadata item; and performing the file operation using the metadata associated with the file.

A content management system interface at a local computer device configured to receive user file commands from a file manager and translate the user file commands into content management commands for sending to the remote content management system via a network interface. The content management system interface is further be configured to receive remote file information from the remote content management system via the network interface and translate the remote file information into user file information for the file manager.

One example method includes receiving a set of filesystem parameters, creating a simulated filesystem based on the filesystem parameters, receiving a set of target characteristics for a file collection, based on the target characteristics, slicing a datastream into a grouping of data slices, populating the simulated files with the data slices to create the file collection and forward or reverse morphing the file collection from one generation to another without rewriting the entire file collection.

Described embodiments provide systems and methods for streaming a virtual disk. A first virtual hard disk (VHDX) file can be converted into a read-only VHDX file on a hypervisor. A second VHDX file can be created as a snapshot of the read-only VHDX file on the hypervisor. Partition globally unique identifiers (GUIDs) of the second VHDX file can be updated to be different from those of the read-only VHDX file. A provisioning services server executing on the hypervisor can stream the second VHDX file as a virtual disk over a virtual network established by the hypervisor, by booting the second VHDX file over the virtual network.

This disclosure is directed to embodiments of systems and methods for containerizing files and managing policy data applied to the resulting containers. In some of the disclosed embodiments, a computing system determines that a file stored in storage medium is to be included in a container to be sent to at least one computing component associated with a device including a user interface. The computing system determines that the file is of a particular type and also determines code that can be used to access files of the particular type. The computing system combines the file and the code into the container such that container is configured to be executed by the at least one computing component so as to cause content of the file to be presented by the user interface. The computing system then sends the container to the at least one computing component. In some implementations, the container may further include policy information defining at least one of whether, how, where, when, or by whom the file can be accessed using the code. A communication link may be established between the computing system and the container at the at least one computing component and an instruction may be sent via the communication link that causes a change to the policy information.

One example method includes receiving a set of filesystem parameters, creating a simulated filesystem based on the filesystem parameters, receiving a set of target characteristics for a file collection, based on the target characteristics, slicing a datastream into a grouping of data slices, populating the simulated files with the data slices to create the file collection and forward or reverse morphing the file collection from one generation to another without rewriting the entire file collection.
