The point of it
The idea is to be able to check a set of text files, looking in each to find a string or check dates.
How to do it
Choose a folder, and the case-sensitive mark-up in the texts you want to locate. Then press Start.
If you press the Move button you can then move or copy the files which were found. If moved, they get renamed .moved placed in a sub-folder called moved.
If copied, you get to choose the destination, and they retain their existing path-structure. For example, J:\Mary\Robert\Fatima\Text1 if the destination is J:\Mary\Peter will be saved as J:\Mary\Peter\Fatima\Text1.
