DISKMAP: Object file for program.
User Instructions
Maps extent information for a disk, showing the placement of
files and locations of unused disk extents. The report
produced by the program can be sorted in physical order or by
file name. (Note: the disk to be analyzed must have no files
open during analysis.)
Run the program, specifying the name of the volume to be
analyzed and the sort order of the report (either
(E)xtent or
(F)ile order).
The program will produce a report showing the
starting and ending blocks, file name, file type, number of
extents, and the amount of space allocated and used.
After the report is completed, the program ends.
Programmer Instructions
From a single entry screen, produces a report in the order
specified by the user or program. Since the program requires
exclusive access to the volume to be analyzed,
non-interactive use may be more reliable by attempting to
re-mount the disk for exclusive use and bypassing DISKMAP if
not successful.
MAPINFO Press (RETURN) to continue or PF(16) to exit the
program.
VOLUME (blank) The name of the disk volume to be
analyzed.
SEQUENCE E Sort order for the report. Select
(E)xtent or (F)ile order.
Example of use
Disk performance can often be improved by locating files that
are frequently used closer to the Volume Table of Contents
(VTOC). The extent information given by this and other
programs can help locate these files.
