Need to handle errors in a user friendly manner. Like skipping files that you don't have access to. If there is an exception display it to a text box.

Skip moving files that have not need of renaming.

There are multiple issues with the date renaming and adding

Clear listboxes when done

when moving files to the deleted folder sometimes there are duplicate file names so there needs to be tracking for file names just like the others. Make a method that does this.

Set log file extension to .bak

Don't allow duplicate folder. Also watch for folders that are within other folders.

Show done message with elapsed time. Show message box if console is closed.

add a progress bar to visualize the processing

Show an error when there are not tools selected

The automatic suffix insertion works but when the textbox is cleared it throws a index exception

remove the edge case that skips files that have a modified date of 2007

have historical undo data stored in the text file, only store redo data for the current session in a stack.

Put the renaming on a separate thread from the IO so it doesn't freeze and you can watch the console as it works.
Add loading bar when this is working

reformat the console to be more readable.
