README for Win32::LongPath

This module was developed for the Windows environment. It was tested in
WinXP and Win7 (64-bit) but should work in anything from WinXP to Win8.
It was also tested in the Cygwin 1.7.25 environment.

It was developed in ActivePerl 5.16 but should work with Perl 5.8.0 or later.

Install a C compiler. It has been successfully compiled using MinGW 4.6.2,
MinGW64 4.5.4 or Visual C++ 2010 Express. Please note the following:

  1. It is best to use the same compiler that was used to compile Perl itself.

  2. MinGW 3.4.5 created a DLL that did not work in the WinXP environment.

Make the source code directory the current directory and type the following
commands to create the module, test it and install it. NOTE: Use dmake
instead of nmake if you are using MinGW.

  perl Makefile.PL
  nmake test
  nmake install

The test code will do the following:

  1. Create a very long path in the source directory that includes Unicode
    names. If the path already exists a warning will be displayed.

  2. Create a Unicode file in that directory.

  3. Copy and rename the file.

  4. If the file system, operating system and user privileges support it,
    it will create a hard link, relative symbolic link to a directory,
    and a fullpath symbolic link to a file. A diagnostic message will be
    printed if these conditions are not met. NOTE: Symbolic links require
    Administrator privileges.

  5. Change the read, hidden, system and FANCI attributes of file. A
    diagnostic message will be displayed if the FANCI attribute is not
    supported and it will not test this feature.

  6. The file access and modification times will be changed to 24 hours
    earlier and will be tested for that time. Since some file systems
    do not have 1-second resolution (i.e. FAT) a diagnostic warning will
    be displayed if the access time is not the same and less than a day
    or the modification time is not the same and is less than 2 seconds.

  7. The contents of the directory will be examined using the opendirL

  8. The files and created path will be removed.

NOTE: If the process fails it may leave the long path and files behind.
  Most likely Windows Explorer will not be able to remove it due to its
