Read File Action File Tab
Read text from: The file or string to read text from (required).
Case-sensitive matching: If unchecked, matches are case-insensitive; if checked the case must match when searching.
Dot does not match newline: Causes . (period character) to not match newline characters (negates Perl /s modifier).
Allow comments and ignore white space (Perl extended mode): If checked, white space outside of character classes is (mostly) ignored and anything following an unescaped # character is treated as a comment.
Encoding (code page): The encoding or Windows code page that will be used when reading and writing the file (optional). If left blank, the system code page (CP_ACP) will be used or the encoding specified by the BOM if the file contains a BOM (byte order mark). Other common encodings for files are UTF-8, Unicode (UTF-16 LE), Windows-1252, Cyrillic, Chinese, and other encodings or code pages supported by Windows (see the Microsoft Global Development web site and MSDN Unicode topics for more details).
Convert null bytes to spaces: If checked, any null bytes in a binary file will be converted to spaces. If unchecked, only data up to the first null byte in a binary file will be read.
