Abstract: A system includes a storage subsystem having a data area and a header area. The data area is for storing contents of at least one data file, and the header area is for storing access parameters and status information for accessing each data file individually. The data area and the header area define a storage area in the storage subsystem. Multiple files are efficiently managed based on utilization of the storage area in the storage subsystem.

Abstract: The present application relates to deposit control additive composition comprising of Mannich base and Polyisobutylene amine (PIBA) having average molecular weight of 800 as a synergistic component of deposit control additive formulation. The application also relates to deposit control additive composition comprising further components such as fluidizer oil, dehazer, corrosion inhibitor and solvent to obtain deposit control additive formulation and mixed with gasoline fuel to obtain fuel composition. The application further relates to a process for the preparation of fuel composition by blending at an ambient temperature gasoline fuel and deposit control additive composition obtained by blending in a suitable container Mannich base, Polyisobutylene amine (PIBA), fluidizer oil, dehazer, corrosion inhibitor and solvent at a temperature ranging between 50° C. to 60° C. for a time period of up to 2 hours.
