Windows 9x (win95, win98, win98SE and winME) has a batch file system which does not work fully with long file names, so we recommend that ant and the JDK are installed into directories without spaces, and with 8.3 filenames. The Perl and Python launcher scripts do not suffer from this limitation.
All versions of windows are usually case insensitive, although mounted file systems (Unix drives, Clearcase views) can be case sensitive underneath, confusing patternsets.
Ant can often not delete a directory which is open in an Explorer window. There is nothing we can do about this short of spawning a program to kill the shell before deleting directories.
