PcConverter offers you all kinds of tools you need to convert files from or to many different formats. You can use PcConverter to convert text files (also RTF files) from Windows or Unix to Mac OS, or you can use it to process your custom database files or to automate the conversion of text files to html. Different Operating Systems use different ASCII tables (a way to represent characters) so, for example, when you try to open a Windows™ text files with a Mac OS application all the special characters (like è, à, ? etc.) are misinterpreted and the result is a series of garbage characters. To fix this drawback PcConverter comes with six different tables that enable you to convert text files (Dos, Unix and Windows) and correctly use them in your Mac OS. This is only an example of what you can do with PcConverter because you have also the ability to write your own conversion tables to expand the PcConverter capabilities.
