DATA ACCESS SYSTEM FOR A FILE ACCESS PROCESSOR

A computer system manages storage of files and/or directories. The computer system stores a specification of a file space allocation for an application support processor, an application program, or a group of application programs. The computer system can store temporary files for the application support processor, application program or group of application programs that require greater file space than the file space allocation. This is done by temporarily providing extra unused file space during processing of the temporary files. When the application support processor, application program or group of application programs attempts to commit the files, the file space allocation is enforced. The computer system can store specifications of file space allocations for a plurality of other application support processors, application programs or groups of application programs. The computer system supports a situation where the temporary files for the first application support processor, application program or a group of application programs requires so much file space beyond the allocation for the first application support processor, application program or group of application programs that all of the allocations cannot be satisfied at the time these temporary files are stored.
