Conversion of rar files to doc file format

Typically it is not possible to convert .rar files (RAR compressed archive) to .doc (MS Word document).  But of course it can happen that some .rar files might contain .doc files inside, so in such case just decompress the RAR archive using any tool available. If that doesn't work, your RAR archive is either corrupted or not RAR archive at all.
