Never having lost defrag I haven't tried this however the recommended procedure is select 'defrag.inf' which can be found in the \tools\mtsutil folder on the Windows 98 CD Right-click 'defrag.inf', and choose Install from the menu. Good luck
PS Normally 'Defrag' is found in C:windows.You may want to if see if it is installed before reinstalling. The shortcut to Defrag should be in C: WINDOWS/ Start menu/Programs/Accessories/System tools folder Many users of 98 use the ME degrag as it runs faster. This can be downloaded from click here It is about half way down the page called 'ME Defrag for Win9*'
Thanks for all your advice with it I have found defrag on the system, However, when I right click on a drive and tell to defrag it keeps saying that defrag is not installed on the system and go to control panel add/remove progs and reinstall I have tried this but unable to find defrag to install any clues?
It would seem that the shortcut is missing. You could try creating a shortcut to Defrag from C:Windows, copy(or cut) this and paste it in the C: WINDOWS/Start menu/ Programs/Accessories/System tools folder.(If you copy, delete the shortcut in Windows after pasting it in the system tools folder) This should restore the shortcut, post back if this doesn't work
