Two possibilities why it is not being found.
1] It will not necessarily be in all files.
2] The string may be spread over more than one line. Many
such tools will only work on a single line of a text file, which is

BKReplaceEm.I prefer the former as it is more developed and the
price is not high. Some prefer BKReplaceEm because it is free. Link
on my site or Google it.
