A system and a process for deploying a computer file involves a client computer applying the computer file concurrently with downloading the computer file from a file server. The concurrent operations can be performed even when the data of the computer file is downloaded out of order. The computer file includes a plurality of file segments. The client computer obtains information defining the file segments and monitors the received data of the computer file during downloading. When downloading of a file segment is complete, the client computer applies the completed segment concurrently with receiving other segments of the computer file from the file server. The process can be used when the computer file is downloaded using a multicast protocol, but is not limited to use with multicast protocols. The client computer can request only needed segments of the computer file.

Concurrently applying an image file while it is being downloaded using a multicast protocol

A multicast content provider operates on a multicast server in conjunction with a multicast transmission protocol that is independent of the content data transmitted and allows extensibility in the content provider to distribute any type of content. The content provider module is designed to find, read, write, and transform particular types of data into a form acceptable for transmission by the transmission protocol on the multicast server. The transmission protocol is agnostic to the type, size, format, or location of the data file. The content provider module manages these issues so that the transmission protocol does not have to. This relationship between the content provider module and the transmission protocol establishes a 'generic' multicast solution, capable of complete flexibility with regard to content delivery.

Multicast content provider

A stub directory is written out to a storage device for multiple files in a container file, the stub directory including identifiers of the multiple files but excluding data of the multiple files. In response to a request to access one file of the multiple files, the data of the one file is written out to the storage device. A requested modification is allowed to be performed on the one file written out to the storage device to generate a modified version of the file. After modification of the one file is completed, a previous version of the file in the container file is replaced with the modified version of the file.

Selectively modifying files of a container file

One or more levels of a stub directory from a container file are written out to a storage device. The stub directory initially includes identifiers of one or more directories in the one or more levels of the stub directory but not identifiers of additional directories in the one or more directories. In response to a request to access one of the one or more directories, identifiers of one or more additional directories and/or one or more files in the one directory are extracted from the container file.
