Re: Changing filename extensions

$dir is not the current directory so you are renaming nonexistant files in the current directory.

Either change the current directory to where the files are or include $dir as part of the path when renaming.

Given the OP is a Perl newbie, just a further clarification that when running Perl on Windows, forward slashes are preferred to backslashes. This enhances code portability because they work fine in file paths when using Perl on both Unix and Windows (as described in more detail at Re^4: windows perl and paths) and boosts enjoyment because they are easier to type and read than ugly escaped backslashes. :)	[reply]
