can i open Open office files to microsoft office and vice versa?

yes of course the 2 suites support the same extensions..so if you install and use normally openoffice you can view and modify files created on ms office and vice versa without problems..

you can open Microsoft office files in open office, regardless of the version (like 2003, 2007, etc). Open office provides compatibility for all the microsoft office file equivalents of theirs. Microsoft office however cannot open open office files unless you saved the file in microsoft office format. If i'm not making any sense, here's a simpler example. You have Open Office, for example, Writer. You made a document using Writer and you want to save it. You can save it as an Open Document Text (.odt) which is the default file extension of Writer. You have however the option to save it as a Word Document (.doc or .docx). You can open any file in Writer that has the .odt, .doc or .docx file extension. Makes sense because you can save using these file extensions. In MS Word, You made a document and want to save it, you can save it as either .doc(Office 2003 and before) and .docx(office 2007 and 2010). You can also open both files in MS Word, provided that you are using the latest version. (Using Office 2003 to open .docx files will not work.) You can't open .odt files in MS Word because you can't make odt files in MS Word. The same goes for the rest of the applications in Open Office and MS Office
