I'm guessing this question has something to do with this: <br><a href="http://isatab.sourceforge.net/validator.html">http://isatab.sourceforge.net/validator.html</a><br><br>Which appears to be some sort of Java application that validates "isatab" files, which appear to be related to mentioned magetab files. <br>
<br>I'm further guessing that you thought a .jar file (A Java program archive) would be openable by WinRAR, since it can open .rar files? If so, they are utterly different things. If not, then apologies and please excuse my incorrect inferrence.<br>
<br>It's unclear to me how this question relates to Python though? Are you trying to implement reading/writing/validation of isatab files in Python or something?<br><br>Many thanks,<br><br>Walter<br>
