We get a lot of questions asking how to open Microsoft Publisher files in OOo. OOo cannot open Publisher files. There doesn't seem to be anything out there that will open Publisher files apart from Microsoft Publisher (there isn't even a Microsoft Publisher Viewer in the same way there is a Word Viewer or a PowerPoint Viewer).
However, you can convert Publisher files to Microsoft .doc files using Zamzar
. This is a free on-line service.
Once you have the file(s) in .doc format you should be able to open them in OOo Writer. I have tried some experiments and the conversion to Word works pretty well, but opening that .doc file in Writer is sometimes less successful, and requires some tidying-up. However, at least you have access to your information again.
On Windows at least, you can also open the .doc file in WordPad and then copy all of the text and images and paste them into a new OOo document. It is sometimes quicker to do this and reformat your new OOo document than try to re-work the imported .doc.
