How to replace in files with [] in file name?

[kevina]

Per the help file (Replace in File Action section):
<snip>
Note: To insert literal bracket [ ] and percent sign % characters within this field, they must be doubled up (just as in any other field), since these are normally interpreted by Visual Build Pro as referencing script code and macros within a field.

Simply double up any occurence of [ ] or % in the find or replace text, and check the "Treat all character as literals (no regular expressions)" check box.
