Windows Explorer

Foler Options
View Tab
Click on Show hidden files and folders
You want to delete the .tmp files.
This is correct for Win XP, but not for Win 98.
In Win 98, double click My Computer or start Windows Explorer. Then go to
View menu
Folder Options
View tab
Under Hidden File, select the option for “Show All Files”
Also, a little further down, you might clear (uncheck) the option “Hide file extensions of known file types” if it is selected. This will make it easier to find files of specific types.
Oops. Thanks for the catch RJKUgly.
