On a sidenote... .doc is a proprietary format, thus creating a converter requires either reverse engineering or knowledge of the file structure of a .doc file. (It bears noting that the new file format .docx (and the rest for Office 2007) is an open format and thus the specifications are available).
It does not mean that it's impossible, but it's not easy. ZFR beat me to the links by hours...so I won't mention anything about those. [img]tongue.gif[/img] Alternatively
google provides quite a few links (the first few with trial versions. If you only need to convert one file, then I guess a trial version is perfect.
