delspecial is a "dos world can't do without" file finder / command invoker plus new deltree - 5-star rated. invokes any program / command to do anything the invoked program / command has provision for, on any file or a particular set of files located anywhere on a disk (file extension enough). every command or executable, that will not attend to subdirectories on its own, can be made to be invoked on any files wherever they may be on a drive. delspecial puts every dos command or executable at your disposal. all types of commands and programs can be invoked i.e. those that accept file specifications and those that accept only the full name of the file can be invoked and dos pipe characters can also be employed where necessary using user defined substitute characters. now the entire drive's contents are in your control even when you know only the file extensions instead of full filenames. locates file (file extension enough). logs to file's directory on your behalf. on next invocation, you can skip this directory and go to next level directory which has file(s) with desired extension. versatile. you can do anything. find and open file. find and delete file. lists deleted files in listfile. find and play, view, edit, encrypt, or shred file or do anything if you have the required player, viewer, editor, encrypter, shredder, etc., etc. imagination and programs / commands at your disposal are the only limitation, if it can be put that way. programmers can search for code (often their own code) by invoking a file viewer recursively across directories all over the drive. one can limit functionality to first-file-found directory if recursive directory navigation is not needed. has runtime directory creation capability. fewer command line params to be typed if environment variables are used. setting scroll lock on stops next invocation of specified command or next file deletion.
