SUMMARY

The following article describes how to determine the programs that are optimized by the Windows 98 and Windows Me Disk Defragmenter tool.

MORE INFORMATION

When Disk Defragmenter optimizes programs, it logs information about this optimization in a file named Optlog.txt. The Optlog.txt file is located in the Windows\Applog folder. To determine the programs that are optimized by Disk Defragmenter, use the following steps:
  1. Click Start, point to Find, and then click Files Or Folders.
  2. In the Named box, type optlog.txt, and then click Find Now.
  3. Double-click the Optlog.txt file, and then scroll to the Programs Eligible For Optimization section. Programs that are optimized by Disk Defragmenter are listed under this section.
Disk Defragmenter optimizes a program by moving the executable files and supporting files to a contiguous area of your hard disk. This can significantly decrease the time it takes to start the program.

Programs that are not optimized by Disk Defragmenter are listed under the Programs Ineligible For Optimization section. Note that programs that are not optimized do not have improved start times. These programs are flagged in the Optlog.txt file with the reason the program is not optimized.

Flag Description

S       Log size smaller than <minimum log size>
U       Program not used for more than <maximum no used days>
P       No profile for program
E       Associated program no longer exists
D       Log deleted (may be combined with one of the above)
