Start,

Command (as you are Win 98).
Then, at the command prompt (>), type:
cd\
(press enter) - this gets you to root of the C: drive (C : \ > )
Now to search for any files with the file extension .DBX, type:
dir *.dbx /s
(press enter) - the /s is important, as it forces the search to look in all subdirectories.
Once you have found (and noted) the location of any dbx files, do the same for *.pst, and if you have another hard disk (e.g. D drive), type
D:
to change to the D: drive, and follow the above procedure, (substituting D for C).
