Abstract: An extensible file system format for portable storage media is provided. The extensible file system format includes the specification of primary and secondary directory entry types that may be custom defined. The primary and secondary directory entry types can be further classified as critical and benign directory entries. The directory entry types can define whether a cluster chain corresponding to a file can be contiguously allocated.

Abstract: Storage virtualization techniques that automate the management of content between local storage and cloud storage in a manner that is both flexible and user-friendly are disclosed herein. A smart storage policy engine may be configured to detect the occurrence of one or more events relating to a storage capacity of the computing device, determine, in response to the detection, a need to free an amount of storage of the computing device, and execute one or more policies relating to stored content of the computing device.

Abstract: Storage virtualization techniques allow files to be stored remotely, for example, by a cloud storage provider, but in a manner that appears to a user or application running on a local computing device as if the files are stored locally—even though the data of those files may not be resident on the local computing device. That is, the contents of files that may exist in the cloud look and behave as if they were stored locally on a computing device.

Abstract: Storage virtualization techniques allow directories to be stored remotely, for example, by a cloud storage provider, but in a manner that appears to a user or application running on a local computing device as if the directories are stored locally—even though the data of those directories may not be resident on the local computing device. That is, the contents of directories that may exist in the cloud look and behave as if they were stored locally on a computing device.

Abstract: Disclosed is a method for creating and reading a contiguous file in an extensible file system. During the creation of a file on the storage media, the file system format check the bitmap to determine if there are areas of free space on the media that would permit the storage of the file in a contiguous manner. By storing the file in a contiguous manner the file may later be read without resorting to the file allocation table, because the file itself would not be fragmented on the storage media. Once an area of free space has been identified, the file is written to the media in a contiguous manner. Further, an associated entry for the file in the directory entry is updated or created to indicate that the file is a contiguous file and also provides basic parameters necessary to read the file without resorting to accessing the file allocation table.

Abstract: Storage virtualization techniques allow files and directories to be stored remotely, for example, by a cloud storage provider, but in a manner that appears to a user or application running on a local computing device as if the files are stored locally—even though the data of those files and directories may not be resident on the local computing device. That is, the contents of files and directories that may exist in the cloud look and behave as if they were stored locally on a computing device. The level of hydration of placeholders may be monitored and operations may be performed to reduce the impact of excessive hydration on the resources of the computing device.
