Methods and systems are provided for manipulating data in segmented environments such as an instance of a NetWare file system. Unlike the conventional approach that relies on FDISK and the install.nlm and nwconfig.nlm utilities in NetWare, the invention does not destroy user data on the disk after the data is copied to tape or other intermediate storage. Segment-related features such as limits on the number of segments; various configurations of segments, volumes and partitions among drives; and data mirroring, are handled by the invention during &ldquo;in place&rdquo; manipulations. Segments, volumes, partitions, and segment clusters or blocks may each be resized. Segments may be merged. Volumes may be consolidated on a single drive. Other manipulations and various combinations of manipulations are also provided.

Manipulation of computer volume segments

Methods, systems, articles of manufacture, and signal formats are provided for transferring disk images from a transmitting computer to one or more downloading computers. The transfer is done in a manner that allows a technician to start the download to one computer while preparing a second computer for downloading or shutting down a third computer after it has finished downloading the disk image. The computers need not wait for the beginning of a data stream but can instead join the download at specified points within the data stream. This reduces the time spent waiting to begin the download, particularly when the disk image being transferred is large. Compression and connection selection may be performed in response to changes in network performance. Image file packing and error management techniques may also be used, as well as on-the-fly file system instance manipulations.

A method and system from integrating a headerless apparatus into a messaging environment. The method and system enable message routing capabilities to and from conventionally headerless apparatus, such as scanners and digital copiers. The apparatus work in conjunction with a document router to provide full-featured and secure message routing capabilities, including scanning images directly to an electronic mailbox, and retrieving messages from within the messaging environment for output at the apparatus.

A computer system and method for document indexing and data retrieval. A full text index is created in two phases. In the first phase, a word list symbol table, an alphabetically ordered list, and a non-repeating word number stream are constructed from the source text. In the second phase, a word number access array and in-memory full text index are constructed and then index data is merged into the final index.
