  DIRtools ver 1.16d: Utilities for copying, deleting, and viewing directories

    DELDIR.CMD -- Delete a directory tree
   COPYDIR.CMD -- Copy a directory tree
   DIRTREE.CMD -- Display files in a directory tree
    
                --------------------------------------------

Requirements:

    COPYDIR requires the REXXLIB library. 
    A copy of REXXLIB.DLL is included. 
    COPYDIR also uses ZIP.EXE and FILEREXX.DLL for a few (less frequently 
    used_ options).

    ZIP.EXE can be obtained from ftp://ftp.freesoftware.com/pub/infozip/OS2/.
    FILEREXX is freeware, written by Jeff Glatt (thanks, Jeff, wherever you 
    are!) 

    Further details concerning these requirements are listed in the
    disclaimer at the bottom of this document.

                --------------------------------------------

Installation:

    Just copy the .CMD files to a directory in your path (say, C:\OS2\APPS);
    and copy FILEREXX.DLL and  REXXLIB.DLL to a directory in your libpath 
    (say, C:\OS2\DLL). If you don't have ZIP.EXE, obtain it and install it
    in your path.

    Note that these utilities are designed to be run from an OS/2 command prompt.

                --------------------------------------------
  
Short Descriptions:

For details on the usage and options of these tools, please look at the
various .CMD files.  You can get a short synopsis of these utilities
by entering a ? as an argument (for example: COPYDIR ?). For COPYDIR
and DIRTREE, you can get a more extensive description by entering ??
(for example, COPYDIR ??).


*** DELDIR 

DELDIR is used to delete a directory tree. It will also delete selected
files in & under a directory.

Examples:
   D:>deldir e:\oldjunk
   D:>deldir f:\archive\mystuff "*.bak" -q


*** DIRTREE:

DIRTREE is used to sort and display all files in a single, or in multiple,
directory trees. It is a useful tool for finding multiple occurence
of a given file (or files).

Sorting can be by name, extension, size, and/or date (you can sort by 
multiple criteria); with display in either ascending or descending order.
Other features include file exclusion criteria, saving results in
HTML format with links to found files, and creation of directory summaries.


Example. This will sort and display all *.DOC files in or under
         e:\manyfile\set1, with files sorted by filename, and by 
         date within a file name.

  D:>dirtree e:\manyfile\set1\*.DOC -Ond

Notes:
   *  DIRTREE can use, but does not require, REXXLIB.  However,
      when examining many files (several thousand), the ability to use
      REXXLIB procedures can substantially improve progam speed.

   * DIRTREE.CMD contains several directory oriented procedures that 
     REXX programmers might find useful.

    * DIRTREE can also be used to find duplicate files, with sets of duplicate
      files grouped together (duplicate file find can be conducted with, or without,
      CRC checks).

*** COPYDIR:

COPYDIR will copy the contents of a directory tree to a new location.  Among
it's several features are:
 i) If an error occurs, say due to an uncopyable file, COPYDIR will
    note the error, and go to the next file (it is "robust" against
    failures)
ii) If copying from HPFS to FAT directories, COPYDIR will convert
    longnames to 8.3 names.
iii) COPYDIR will not overwrite newer files in the destination directories.
     Or, you can specify a complex set of replacement rules (such as, "only
     replace if source file is older and bigger").
iv) Instead of copying files from a source to a destination directory,
    COPYDIR can create a "destination directory specific .ZIP file", and
    ZIP the files into it. This retains the original structure of the
    source directory, with the files from these source directories copied to
    seperate .ZIP files in the destination directories.
v)  You can exclude, or selectively include, files & directories 
vi) You can copy files currently being shared (that a normal COPY or XCOPY 
    command will fail on).

Example:
  D:>copydir  e:\oldspot  f:\archive\oldspot   -8 -Rnb


For details on COPYDIR, run COPYDIR with an argument of ??.
