Dynamic file mapping for network computers

Abstract

File mappings are dynamically loaded within an operating data processing system appended to existing file or directory mappings during operation rather than being loaded during system initialization. A triggering event, such as a user logging into a network from the data processing system with a unique userid, initiates the process for selectively loaded the dynamic file mappings. A context variable, such as the userid of the user logging into the network, is employed to select the set or table of file mappings which are dynamically loaded. The dynamically loaded file mappings are appended to traditional, machine-specific file mappings loaded at system initialization and may be unloaded without affecting such traditional file mappings. The capability of dynamic file mapping allows single-user applications, those designed for use by only one user at a time, to be shared from a single network location, with user-specific files mapped to different locations for different users. Thus, only one copy of a browser is required in a network computer environment. Sensitive files, such as bookmark, security, and cookie files, are dynamically mapped to a user-specific directory based on the userid regardless of the user unit from which the user logs in. Multiple users may share a single copy of the single user browser, and users may “roam” the network, logging in at any data processing system.
