This progrAM adds an AppendDate item to the context menu of files and folders to allow the user to append the date to the end of the file/folder name. For example, if you have a file called MyFile.txt and used AppendDate it would change the file name to MyFile_20121105.txt. The date format can be changed in the settings and you can also prepend (prefix) the date.
