    Abstract: Methods and systems of managing data files are described herein. One method includes updating a container file of data files having a container file metadata section and one or more empty records, each record of the one or more empty records having: (i) a data file section reserved for storing a data file, (ii) a file metadata section reserved for storing metadata about the data file, and (iii) a record metadata section including information about the record and having at least a record status mark indicating that the record is empty. The method includes setting the record status mark of the one or more empty records to being updated; writing one or more records containing the data file into the one or more empty records within the container file. After successfully writing the one or more records resetting the record status mark to valid.

    Abstract: A method and system for requesting information from a server are provided. The method may include sending, by a client to a server, an HTTP GET request to retrieve at least a portion of at least one derived data file, the at least one derived data file being dynamically generated by the server in response to the request using a data file virtualization policy and at least a portion of a data file. The data file virtualization policy and the data file may be stored in a storage accessible by the server, and the dynamic generation may comprise an aligned unbuffered direct read operation from the stored data file of a data size that is aligned to an integer multiple of the storage's block size. The at least the portion of the at least one derived data file may then be received by the client from the server.

    Abstract: A method of inserting an image into a container file including reading source data including the image; opening the container file where the image will be stored, the container file comprising one or more records. Each record includes an image file section reserved for storing the image, an image metadata section reserved for storing data about the image, and a record metadata section having a status flag or status mark indicating whether the image file section is empty. The method further includes determining whether the source data is valid to be entered into a record in the one or more records; if the source of data is valid, preparing the record and the image metadata; and writing the record into the container file and marking the status mark of the record as being updated while writing the record into the container file.
