There is a Find/Replace function under the Edit menu. You must first click in the Explorer View before you can select this option from the menu.

This function is case sensitive. If you select Find Next then the next occurrence of your Find what string will be highlighted in the Explorer Window.

The Replace function is most useful if you have, for instance, renamed an exit program. This will replace the currently found Find what string with the Replace with sting.

The Replace All will replace all occurrences,in the Explorer View, of the Find what string with the Replace with sting without asking.

Click Cancel if you wish to end the Find/Replace function.
