my_wc
This tools is a almost the same as wc for UNIX, it tells you how many files you have selected, in these files, how many lines, words and characters there is, it's useful to place this tool in the SendTo menu to quickly get informations about your files (for example, very usefull to see number of lines of code in a project)
To use it, you just have to drop files on it, or running it with filenames as parameters
