What is the most recent Microsoft Word save file format?

Of those options, Microsoft Word 97/2000/XP is the most recent.

Would the person i send it to have an issue opening it? On the job posting it only says “Must email as MS Word only.”

There should be no problem. It’s still a recent format, and any new edition of Microsoft Word should be able to open all previous formats.

Quite an annoying requirement, but indeed, hopefully the conversion to the XP format will work out fine – they should then be able to open it. (Which version of OpenOffice are you using? It should by now also have support for .docx, the latest version. Development of OpenOffice stagnated a bit since OpenOffice bought it and subseuently did nothing with it until giving it away a year later, so you might want to try LibreOffice, which split off from OpenOffice and is developed much more actively (and thus should be more up-to-date).

@Vincentt I’ve never found OpenOffice to handle Open XML formats well. As such, it seems safer to me to just stick with the XP format for now. Good point about LibreOffice, though.

It should be a .docx extension, if that helps.

@Mariah That’s the file extension of the new Open XML format, but Word can still open Microsoft’s proprietary .doc format.

As @Mariah stated, it is .docx

LibreOffice worked perfectly, Thank you!
